The VNIC driver's "login" command sequence is the final step
in the driver's initialization process with device firmware,
confirming the available device queue resources to be utilized
by the driver. Under high system load, firmware may not respond
to the request in a timely manner or may abort the request. In
such cases, the driver should reattempt the login command
sequence. In case of a device error, the number of retries
is bounded.

On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS allmulti setting does not allow
unregistered mcast packets to pass.
This happens, because ALE VLAN entries on these SoCs do not contain port
masks for reg/unreg mcast packets, but instead store indexes of
ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for
reg/unreg mcast packets.
This path was missed by commit 9d1f644727 ("net: ethernet: ti: ale: fix

Only QMAP endpoints should be configured to find a pad size field
within packet headers. They are found in the first byte of the QMAP
header (and the hardware fills only the 6 bits in that byte that
constitute the pad_len field).
The RMNet driver assumes the pad_len field is valid for received
packets, so we want to ensure the pad_len field is filled in that
case. That driver also assumes the length in the QMAP header
includes the pad bytes.
The RMNet driver does *not* pad the packets it sends, so the pad_len
field can be ignored.
Fix ipa_endpoint_init_hdr_ext() so it only marks the pad field
offset valid for QMAP RX endpoints, and in that case indicates
that the length field in the header includes the pad bytes.

The way the mask value is programmed for QMAP RX endpoints was based
on some wrong assumptions about the way metadata containing the QMAP
mux_id value is formatted. The metadata value supplied by the
modem is *not* in QMAP format, and in fact contains the mux_id we
want in its (big endian) low-order byte. That byte must be written
by the IPA into offset 1 of the QMAP header it inserts before the
received packet.
QMAP TX endpoints *do* use a QMAP header as the metadata sent with
each packet. The modem assumes this, and based on that assumes the
mux_id is in the second byte. To match those assumptions we must
program the modem TX (QMAP) endpoint HDR register to indicate the
metadata will be found at offset 0 in the message header.
The previous configuration managed to work, but it was not working
correctly. This patch fixes a bug whose symptom was receipt of
messages containing the wrong QMAP mux_id.
In fixing this, get rid of ipa_rmnet_mux_id_metadata_mask(), which
was more or less defined so there was a separate place to explain
what was happening as we generated the mask value. Instead, put a
longer description of how this works above ipa_endpoint_init_hdr(),
and define the metadata mask to use as a simple constant.

After an XSK is closed, the relevant structures in the channel are not
zeroed. If an XSK is opened the second time on the same channel without
recreating channels, the stray values in the structures will lead to
incorrect operation of queues, which causes CQE errors, and the new
socket doesn't work at all.
This patch fixes the issue by explicitly zeroing XSK-related structs in
the channel on XSK close. Note that those structs are zeroed on channel
creation, and usually a configuration change (XDP program is set)
happens on XSK open, which leads to recreating channels, so typical XSK
usecases don't suffer from this issue. However, if XSKs are opened and
closed on the same channel without removing the XDP program, this bug
reproduces.

Link speeds are communicated over virtchnl using an enum
virtchnl_link_speed. Currently, the highest link speed is 40Gbps which
leaves us unable to reflect some speeds that an ice VF is capable of.
This causes link speed to be misreported on the iavf driver.
Allow for communicating link speeds using Mbps so that the proper speed can
be reported for an ice VF. Moving away from the enum allows us to
communicate future speed changes without requiring a new enum to be added.
In order to support communicating link speeds over virtchnl in Mbps the
following functionality was added:
- Added u32 link_speed_mbps in the iavf_adapter structure.
- Added the macro ADV_LINK_SUPPORT(_a) to determine if the VF
driver supports communicating link speeds in Mbps.
- Added the function iavf_get_vpe_link_status() to fill the
correct link_status in the event_data union based on the
ADV_LINK_SUPPORT(_a) macro.
- Added the function iavf_set_adapter_link_speed_from_vpe()
to determine whether or not to fill the u32 link_speed_mbps or
enum virtchnl_link_speed link_speed field in the iavf_adapter
structure based on the ADV_LINK_SUPPORT(_a) macro.
- Do not free vf_res in iavf_init_get_resources() as vf_res will be
accessed in iavf_get_link_ksettings(); memset to 0 instead. This
memory is subsequently freed in iavf_remove().

The netif_running() test looks at __LINK_STATE_START which
gets set before ndo_open() is called, there is a window of
time between that and when the queues are actually ready to
be run. If ionic_check_link_status() notices that the link is
up very soon after netif_running() becomes true, it might try
to run the queues before they are ready, causing all manner of
potential issues. Since the netdev->flags IFF_UP isn't set
until after ndo_open() returns, we can wait for that before
we allow ionic_check_link_status() to start the queues.
On the way back to close, __LINK_STATE_START is cleared before
calling ndo_stop(), and IFF_UP is cleared after. Both of
these need to be true in order to safely stop the queues

The dynamic key update for addr_list_lock still causes troubles,
for example the following race condition still exists:
CPU 0: CPU 1:
(RCU read lock) (RTNL lock)
dev_mc_seq_show() netdev_update_lockdep_key()
-> lockdep_unregister_key()
-> netif_addr_lock_bh()
because lockdep doesn't provide an API to update it atomically.
Therefore, we have to move it back to static keys and use subclass
for nest locking like before.
In commit 1a33e10e4a ("net: partially revert dynamic lockdep key
changes"), I already reverted most parts of commit ab92d68fc2
("net: core: add generic lockdep keys").
This patch reverts the rest and also part of commit f3b0a18bb6
("net: remove unnecessary variables and callback"). After this
patch, addr_list_lock changes back to using static keys and
subclasses to satisfy lockdep. Thanks to dev->lower_level, we do
not have to change back to ->ndo_get_lock_subclass().
And hopefully this reduces some syzbot lockdep noises too.

Patch series "mm: consolidate definitions of page table accessors", v2.
The low level page table accessors (pXY_index(), pXY_offset()) are
duplicated across all architectures and sometimes more than once. For
instance, we have 31 definition of pgd_offset() for 25 supported
architectures.
Most of these definitions are actually identical and typically it boils
down to, e.g.
static inline unsigned long pmd_index(unsigned long address)
{
return (address >> PMD_SHIFT) & (PTRS_PER_PMD - 1);
}
static inline pmd_t *pmd_offset(pud_t *pud, unsigned long address)
{
return (pmd_t *)pud_page_vaddr(*pud) + pmd_index(address);
}
These definitions can be shared among 90% of the arches provided
XYZ_SHIFT, PTRS_PER_XYZ and xyz_page_vaddr() are defined.
For architectures that really need a custom version there is always
possibility to override the generic version with the usual ifdefs magic.
These patches introduce include/linux/pgtable.h that replaces
include/asm-generic/pgtable.h and add the definitions of the page table
accessors to the new header.
This patch (of 12):
The linux/mm.h header includes <asm/pgtable.h> to allow inlining of the
functions involving page table manipulations, e.g. pte_alloc() and
pmd_alloc(). So, there is no point to explicitly include <asm/pgtable.h>
in the files that include <linux/mm.h>.
The include statements in such cases are remove with a simple loop:
for f in $(git grep -l "include <linux/mm.h>") ; do
sed -i -e '/include <asm\/pgtable.h>/ d' $f
done

While trying to use the lantiq_gswip driver on one of my boards I made
a mistake when specifying the phy-mode (because the out-of-tree driver
wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the
following error is printed multiple times:
Unsupported interface: 3
While it gives at least a hint at what may be wrong it is not very user
friendly. Print the human readable phy-mode and also which port is
configured incorrectly (this hardware supports ports 0..6) to improve
the cases where someone made a mistake.

The driver registers three different types of thermal zones: For the
ASIC itself, for port modules and for gearboxes.
Currently, all three types use the same get_trend() callback which does
not work correctly for the ASIC thermal zone. The callback assumes that
the device data is of type 'struct mlxsw_thermal_module', whereas for
the ASIC thermal zone 'struct mlxsw_thermal' is passed as device data.
Fix this by using one get_trend() callback for the ASIC thermal zone and
another for the other two types.

When the PHY's strap register is read to determine if lane swapping is
needed the phy_read_mmd returns the value back into the ret variable.
If the call to read the strap fails the failed value is returned. If
the call to read the strap is successful then ret is possibly set to a
non-zero positive number. Without reseting the ret value to 0 this will
cause the parse DT function to return a failure.

This fixes a crash introduced by recent is_kdump_kernel() check.
The source of the crash is that kdump kernel can be loaded on a
system with already created VFs. But for such VFs, it will follow
a logic path of PF and eventually crash.
Thus, we are partially reverting back previous changes and instead
use is_kdump_kernel is a single init point of PF init, where we
disable SRIOV explicitly.

instead of 'base' as the port number. But 'base_addr' isn't equal to
'addr' for all PHYs inside the package, which leads to the Serdes still

skb/xdp_buff headroom should be *at least* equal to one of the values

So, fix the check to align the value up. This satisfies both

Th referenced change added an extra hw reset to rtl8169_net_suspend()
what makes WoL fail on few chip versions. Therefore skip the extra
reset if we're going down and WoL is enabled.
In rtl_shutdown() rtl8169_hw_reset() is called by rtl8169_net_suspend()
already if needed, therefore avoid issues issue by removing the extra
call. The fix was tested on a system with RTL8168g.
Meanwhile rtl8169_hw_reset() does more than a hw reset and should be
renamed. But that's net-next material.

The u64_stats mechanism uses sequence counters to protect against 64-bit
values tearing on 32-bit architectures. Updating u64_stats is thus a
sequence counter write side critical section where preemption must be
disabled.
For mdiobus_stats_acct(), disable preemption upon the u64_stats update.
It is called from process context through mdiobus_read() and

If the geneve interface is in collect_md (external) mode, it can't send any
packets submitted directly to its net interface, as such packets won't have
metadata attached. This is expected.
However, the kernel itself sends some packets to the interface, most
notably, IPv6 DAD, IPv6 multicast listener reports, etc. This is not wrong,
as tunnel metadata can be specified in routing table (although technically,
that has never worked for IPv6, but hopefully will be fixed eventually) and
then the interface must correctly participate in IPv6 housekeeping.
The problem is that any such attempt increases the tx_error counter. Just
bringing up a geneve interface with IPv6 enabled is enough to see a number
of tx_errors. That causes confusion among users, prompting them to find
a network error where there is none.
Change the counter used to tx_dropped. That better conveys the meaning
(there's nothing wrong going on, just some packets are getting dropped) and
hopefully will make admins panic less.

This patch fixes two issues with XDP:
1. If the XDP verdict is XDP_ABORTED we break the loop, which results in
us handling one buffer per napi cycle instead of the total budget
(usually 64). To overcome this simply change the xdp_verdict check to
!= XDP_PASS. When the verdict is XDP_PASS, the skb is not expected to
be NULL.
2. Update the residual budget for XDP_DROP and XDP_ABORTED, since
packets are handled in these cases.

100GbE Intel Wired LAN Driver Updates 2020-05-31
This series contains updates to the ice driver only.
Brett modifies the driver to allow users to clear a VF's
administratively set MAC address on the PF. Fixes the driver to
recognize an existing VLAN tag when DMAC/SMAC is enabled in a packet.
Fixes an issue, so that VF's are reset after any VF port VLAN
modifications are made on the PF. Made sure the register QRXFLXP_CNTXT
is cleared before writing a new value to ensure the previous value is
not passed forward. Updates the PF to allow the VF to request a reset
as soon as it has been initialized. Fixes an issue to ensure when a VSI
is created, it uses the current coalesce value, not the default value.
Paul allows untrusted VF's to add 16 filters.
Dan increases the timeout needed after a PFR to allow ample time for
package download.
Chinh adjust the define value for the number of PHY speeds we currently
support. Changes the driver to ignore EMODE error when configuring the
PHY.
Jesse fixes an issue which was preventing a user from configuring the
interface before bringing it up.
Henry fixes the logic for adding back perfect flows after flow director
filter does a deletion.
Bruce fixes line wrappings to make it more consistent.

Leave congestion group taildrop enabled for all traffic classes
when PFC is enabled. Notification threshold is low enough such
that it will be hit first and this also ensures that FQs on
traffic classes which are not PFC enabled won't drain the buffer
pool.
FQ taildrop threshold is kept disabled as long as any form of
flow control is on. Since FQ taildrop works with bytes, not number
of frames, we can't guarantee it will not interfere with the
congestion notification mechanism for all frame sizes.

Add support in dpaa2-eth for PFC (Priority Flow Control)
through the DCB ops.
Instruct the hardware to respond to received PFC frames.
Current firmware doesn't allow us to selectively enable PFC
on the Rx side for some priorities only, so we will react to
all incoming PFC frames (and stop transmitting on the traffic
classes specified in the frame).
Also, configure the hardware to generate PFC frames based on Rx
congestion notifications. When a certain number of frames accumulate in
the ingress queues corresponding to a traffic class, priority flow
control frames are generated for that TC.
The number of PFC traffic classes available can be queried through
lldptool. Also, which of those traffic classes have PFC enabled is also
controlled through the same dcbnl_rtnl_ops callbacks.

Now that we have congestion group taildrop configured at all
times, we can afford to increase the frame queue taildrop
threshold; this will ensure a better response when receiving
bursts of large-sized frames.
Also decouple the buffer pool count from the Rx FQ taildrop
threshold, as above change would increase it too much. Instead,
keep the old count as a hardcoded value.
With the new limits, we try to ensure that:
* we allow enough leeway for large frame bursts (by buffering
enough of them in queues to avoid heavy dropping in case of
bursty traffic, but when overall ingress bandwidth is manageable)
* allow pending frames to be evenly spread between ingress FQs,
regardless of frame size
* avoid dropping frames due to the buffer pool being empty; this
is not a bad behaviour per se, but system overall response is
more linear and predictable when frames are dropped at frame
queue/group level.

The increase in number of ingress frame queues means we now risk
depleting the buffer pool before the FQ taildrop kicks in.
Congestion group taildrop allows us to control the number of frames that
can accumulate on a group of Rx frame queues belonging to the same
traffic class. This setting coexists with the frame queue based
taildrop: whichever limit gets hit first triggers the frame drop.

equal to the number of configured flows x number of configured
traffic classes.
Current driver configuration directs all incoming traffic to
FQs corresponding to TC0, leaving all other priority levels unused.

configuring the FQs associated with all priority levels, not just
TC0. All settings that are per-TC, such as those related to

Tun in IFF_NAPI_FRAGS mode calls napi_gro_frags. Unlike netif_rx and
netif_gro_receive, this expects skb->data to point to the mac layer.
But skb_probe_transport_header, __skb_get_hash_symmetric, and
xdp_do_generic in tun_get_user need skb->data to point to the network
header. Flow dissection also needs skb->protocol set, so
eth_type_trans has to be called.
Ensure the link layer header lies in linear as eth_type_trans pulls
ETH_HLEN. Then take the same code paths for frags as for not frags.
Push the link layer header back just before calling napi_gro_frags.
By pulling up to ETH_HLEN from frag0 into linear, this disables the
frag0 optimization in the special case when IFF_NAPI_FRAGS is used
with zero length iov[0] (and thus empty skb->linear).

Microchip lan7431 is frequently connected to a phy. However, it
can also be directly connected to a MII remote peer without
any phy in between. For supporting such a phyless hardware setup
in Linux we utilized phylib, which supports a fixed-link
configuration via the device tree. And we added support for
defining the connection type R/GMII in the device tree.
New behavior:
-------------
. The automatic speed and duplex detection of the lan743x silicon
between mac and phy is disabled. Instead phylib is used like in
other typical Linux drivers. The usage of phylib allows to
specify fixed-link parameters in the device tree.
. The device tree entry phy-connection-type is supported now with
the modes RGMII or (G)MII (default).
Development state:
------------------
. Tested with fixed-phy configurations. Not yet tested in normal
configurations with phy. Microchip kindly offered testing
as soon as the Corona measures allow this.
. All review findings of Andrew Lunn are included

We currently have an Rx listener function for exception traps that marks
received skbs with 'offload_fwd_mark' and injects them to the kernel's
Rx path. The marking is done because all these exceptions occur during
L3 forwarding, after the packets were potentially flooded at L2.
A subsequent patch will add support for control traps. Packets received
via some of these control traps need different handling:
1. Packets might not need to be marked with 'offload_fwd_mark'. For
example, if packet was trapped before L2 forwarding
2. Packets might not need to be injected to the kernel's Rx path. For
example, sampled packets are reported to user space via the psample
module
Factor out a common Rx listener function that only reports trapped
packets to devlink. Call it from mlxsw_sp_rx_no_mark_listener() and
mlxsw_sp_rx_mark_listener() that will inject the packets to the kernel's
Rx path, without and with the marking, respectively.

The removal of mips_swiotlb_ops exposed a problem in octeon_mgmt Ethernet
driver. mips_swiotlb_ops had an mb() after most of the operations and the
removal of the ops had broken the receive functionality of the driver.
My code inspection has shown no other places except
octeon_mgmt_rx_fill_ring() where an explicit barrier would be obviously
missing. The latter function however has to make sure that "ringing the

When proxy mode is enabled the vxlan device might reply to Neighbor
Solicitation (NS) messages on behalf of remote hosts.
In case the NS message includes the "Source link-layer address" option
[1], the vxlan device will use the specified address as the link-layer
destination address in its reply.
To avoid an infinite loop, break out of the options parsing loop when
encountering an option with length zero and disregard the NS message.
This is consistent with the IPv6 ndisc code and RFC 4886 which states
that "Nodes MUST silently discard an ND packet that contains an option
with length zero" [2].

will be set to the driver defaults of AIM on, Rx/Tx ITR 50, and INTRL 0.
This is causing issues with how the ethtool layer gets the current

set the coalesce settings globally (i.e. ethtool -C eth0) and use q_vector

Until recently, the Micrel KSZ9031 PHY driver ignored any PHY mode
("RGMII-*ID") settings, but used the hardware defaults, augmented by
explicit configuration of individual skew values using the "*-skew-ps"
DT properties. The lack of PHY mode support was compensated by the
EtherAVB MAC driver, which configures TX and/or RX internal delay
itself, based on the PHY mode.
However, now the KSZ9031 driver has gained PHY mode support, delays may
be configured twice, causing regressions. E.g. on the Renesas
Salvator-X board with R-Car M3-W ES1.0, TX performance dropped from ca.
400 Mbps to 0.1-0.3 Mbps, as measured by nuttcp.
As internal delay configuration supported by the KSZ9031 PHY is too
limited for some use cases, the ability to configure MAC internal delay
is deemed useful and necessary. Hence a proper fix would involve
splitting internal delay configuration in two parts, one for the PHY,
and one for the MAC. However, this would require adding new DT
properties, thus breaking DTB backwards-compatibility.
Hence fix the regression in a backwards-compatibility way, by letting
the EtherAVB driver mask the PHY mode when it has inserted a delay, to
avoid the PHY driver adding a second delay. This also fixes messages
like:
Micrel KSZ9031 Gigabit PHY e6800000.ethernet-ffffffff:00: *-skew-ps values should be used only with phy-mode = "rgmii"
as the PHY no longer sees the original RGMII-*ID mode.
Solving the issue by splitting configuration in two parts can be handled
in future patches, and would require retaining a backwards-compatibility
mode anyway.

This series contains updates to the ice driver only.
Anirudh (Ani) adds a poll for reset completion before proceeding with
driver initialization when the DDP package fails to load and the firmware
issues a core reset.
Jake cleans up unnecessary code, since ice_set_dflt_vsi_ctx() performs a
memset to clear the info from the context structures. Fixed a potential
double free during probe unrolling after a failure. Also fixed a
potential NULL pointer dereference upon register_netdev() failure.
Tony makes two functions static which are not called outside of their

Brett refactors the ice_ena_vf_mappings(), which was doing the VF's MSIx
and queue mapping in one function which was hard to digest. So create a
new function to handle the enabling MSIx mappings and another function
to handle the enabling of queue mappings. Simplify the code flow in
ice_sriov_configure(). Created a helper function for clearing
VPGEN_VFRTRIG register, as this needs to be done on reset to notify the
VF that we are done resetting it. Fixed the initialization/creation and
reset flows, which was unnecessarily complicated, so separate the two
flows into their own functions. Renamed VF initialization functions to
make it more clear what they do and why. Added functionality to set the
VF trust mode bit on reset. Added helper functions to rebuild the VLAN
and MAC configurations when resetting a VF. Refactored how the VF reset
is handled to prevent VF reset timeouts.

The dynamic configuration interface for the General Params and the L2
Lookup Params tables was copy-pasted between E/T devices and P/Q/R/S
devices. Nonetheless, these interfaces are bitwise different.
The driver is using dynamic reconfiguration of the General Parameters
table for the port mirroring feature, which was therefore broken on
P/Q/R/S.
Note that this patch can't be backported easily very far to stable trees
(since it conflicts with some other development done since the
introduction of the driver). So the Fixes: tag is purely informational.

Be there 2 switches spi/spi2.0 and spi/spi2.1 in a cross-chip setup,
both under the same VLAN-filtering bridge, both in the
SJA1105_VLAN_BEST_EFFORT state.
If we try to change the VLAN state of one of the switches (to
SJA1105_VLAN_FILTERING_FULL) we get the following error:
devlink dev param set spi/spi2.1 name best_effort_vlan_filtering value
false cmode runtime
[ 38.325683] sja1105 spi2.1: Not allowed to overcommit frame memory.
L2 memory partitions and VL memory partitions share the

allowed to be larger than 929 128-byte blocks (or 910

l2-forwarding-parameters-table.part_spc and/or
vl-forwarding-parameters-table.partspc.
[ 38.356803] sja1105 spi2.1: Invalid config, cannot upload
This is because the spi/spi2.1 switch doesn't support tagging anymore in
the SJA1105_VLAN_FILTERING_FULL state, so it doesn't need to have any
retagging rules defined. Great, so it can use more frame memory
(retagging consumes extra memory).
But the built-in low-level static config checker from the sja1105 driver
says "not so fast, you've increased the frame memory to non-retagging
values, but you still kept the retagging rules in the static config".
So we need to rebuild the VLAN table immediately before re-uploading the
static config, operation which will take care, based on the new VLAN
state, of removing the retagging rules.

PHYs using the vsc8574_probe fail to be initialized and their

"could not attach PHY: -5".
This is because when the conversion of the MSCC PHY driver to use the

base PHY read and write helpers in the driver were modified. In
particular, the base address retrieval logic was moved from the
config_init to the probe. But the vsc8574_probe was forgotten. This

Set F2 blocksize to 256 bytes and watermark to 0x40 for 4354/4356 SDIO.
Also enable and configure F1 MesBusyCtrl. It would resolve random driver
crash issue.

When wlcore_fw_status() returns an error code, a pairing
runtime PM usage counter decrement is needed to keep the
counter balanced. It's the same for all error paths after
wlcore_fw_status().

The CCK TX setting when switch channel will fix the CCK to
path A only, so if the antenna is configured to path B
(e.g. iw phy set antenna 0x2 0x3 "TX B/RX AB"), then the CCK
packets can never be delivered to the air if only path B is
connected with an antenna (it can possibly be transmitted
through path A, but as path B is configured, the expected
behavior is incorrect).
This can also solve the racing issue of CCK TX setting between
driver and firmware. The CCK TX setting in driver should be
removed. Otherwise, the CCK TX setting would be wrong when the
racing occurs.
