It was possible to delete only one half of an IPv6, which would leave

checking for the unused bitmap, we need to check the unique bitmap, and
refuse any deletion that does not match that criteria. We also need to
move that check from bcm_sf2_cfp_rule_del_one() into its caller:
bcm_sf2_cfp_rule_del() otherwise we would not be able to delete second

We had several issues that would make the programming of IPv6 rules both
inconsistent and error prone:
- the chain ID that we would be asking the hardware to put in the
packet's Broadcom tag would be off by one, it would return one of the
two indexes, but not the one user-space specified
- when an user specified a particular location to insert a CFP rule at,
we would not be returning the same index, which would be confusing if
nothing else
- finally, like IPv4, it would be possible to overflow the last entry by
re-programming it
Fix this by swapping the usage of rule_index[0] and rule_index[1] where
relevant in order to return a consistent and correct user-space
experience.

0..126 instead of the full 0..127 range. This would lead us to allow
overwriting the last rule when we let the kernel pick-up the location.

The micrel KSZ9031 phy has a optional clock pin (CLK125_NDO) which can be
used as reference clock for the MAC unit. The clock signal must meet the
RGMII requirements to ensure the correct data transmission between the
MAC and the PHY. The KSZ9031 phy does not fulfill the duty cycle
requirement if the phy is configured as slave. For a complete
describtion look at the errata sheets: DS80000691D or DS80000692D.
The errata sheet recommends to force the phy into master mode whenever
there is a 1000Base-T link-up as work around. Only set the
"micrel,force-master" property if you use the phy reference clock provided
by CLK125_NDO pin as MAC reference clock in your application.
Attenation, this workaround is only usable if the link partner can
be configured to slave mode for 1000Base-T.

problem, VF pci device should be removed before PF pci device is removed.
This patch moves pci_enable/disable_sriov from hclge to hns3 to solve

Add a driver for Microsemi Ocelot Ethernet switch support.
This makes two modules:
mscc_ocelot_common handles all the common features that doesn't depend on
how the switch is integrated in the SoC. Currently, it handles offloading
bridging to the hardware. ocelot_io.c handles register accesses. This is
unfortunately needed because the register layout is packed and then depends
on the number of ports available on the switch. The register definition
files are automatically generated.
ocelot_board handles the switch integration on the SoC and on the board.
Frame injection and extraction to/from the CPU port is currently done using
register accesses which is quite slow. DMA is possible but the port is not
able to absorb the whole switch bandwidth.

kernel: b43-phy1 debug: Out of order TX status report on DMA ring 1. Expected 116, but got 126
The TX ring alternates between 2 sequences; the ring seems
to be completely confused. Controller restart is needed.
Workaround(1):
This problem doesn't occur when using propriatory firmware
you will extract by b43-fwcutter, so it may be a bug in
openfwwf firmware, as the comment in the b43_dma_handle_txstatus() suggests.
I wasn't able to find a bug in the terse openfwwf code though.
Workaround(2):
Using "pio=1" option to not use DMA makes this problem to
not occur.
Description of the patch:
This patch will forcibly reset the controller to make it
work again. Very kludgy and doesn't look right, but
the traffic will continue to flow.

On the Allwinner R40 SoC, the "GMAC clock" register is in the CCU
address space. Using a standard syscon to access it provides no
coordination with the CCU driver for register access. Neither does
it prevent this and other drivers from accessing other, maybe critical,
clock control registers. On other SoCs, the register is in the "system
control" address space, which might also contain controls for mapping
SRAM to devices or the CPU. This hardware has the same issues.
Instead, for these types of setups, we let the device containing the
control register create a regmap tied to it. We can then get the device
from the existing syscon phandle, and retrieve the regmap with
dev_get_regmap().

On the Allwinner R40, the "GMAC clock" register is located in the CCU
block, at a different register address than the other SoCs that have
it in the "system control" block.
This patch converts the use of regmap to regmap_field for mapping and
accessing the syscon register, so we can have the register address in
the variants data, and not in the actual register manipulation code.
This patch only converts regmap_read() and regmap_write() calls to
regmap_field_read() and regmap_field_write() calls. There are some
places where it might make sense to switch to regmap_field_update_bits(),
but this is not done here to keep the patch simple.

The pfc related priority stats are already handled separately as these

Worse, the sizeof will be incorrect, as it will be the total size of the

Calling the variable l3edev was relevant when neighbor lookup was the
last stage in the simulated pipeline. Now that mlxsw handles bridges and
vlan devices as well, calling it "L3" is a misnomer.
Thus in mlxsw_sp_span_dmac(), rename to "dev", because that function is
just a service routine where the distinction between tunnel and egress
device isn't necessary.
In mlxsw_sp_span_entry_tunnel_parms_common(), rename to "edev" to

Add rudimentary phylink support to mv88e6xxx. This allows the driver
using user ports with fixed links to keep operating normally. User ports
with normal PHYs are not affected since the switch automatically manages
their link parameters. User facing ports which use a SFP/SFF with a
non-fixed link mode might require a call to phylink_mac_change() to
operate properly.

Make the bcm_sf2 driver implement phylink_mac_ops since it needs to
support a wide variety of network interfaces: internal & external MDIO
PHYs, fixed PHYs, MoCA with MMIO link status.
A large amount of what needs to be done already exists under
bcm_sf2_sw_adjust_link() so we are essentially breaking this down into
the necessary operation for PHYLINK to work: mac_config, mac_link_up,
mac_link_down and validate. We can now entirely get rid of most of what
fixed_link_update() provided because only the link information is actually
necessary. We still have to force DUPLEX_FULL for legacy Device Tree bindings
that did not specify that before.

There was a regression at some point from the intended functionality of
commit f60c3704e8 ("bonding: Fix alb mode to only use first level
vlans.")
Given the return value vlan_get_encap_level() we need to store the nest
level of the bond device, and then compare the vlan's encap level to
this. Without this, this check always fails and learning packets are
never sent.
In addition, this same commit caused a regression in the behavior of
balance_alb, which requires learning packets be sent for all interfaces
using the slave's mac in order to load balance properly. For vlan's
that have not set a user mac, we can send after checking one bit.
Otherwise we need send the set mac, albeit defeating rx load balancing
for that vlan.

Since commit 29a5dcae27 ("nfp: flower: offload phys port MTU change") we
take encapsulation headroom into account when calculating the max allowed
MTU. This is unnecessary as the max MTU advertised by firmware should have
already accounted for encap headroom.
Subtracting headroom twice brings the max MTU below what's necessary for
some deployments.

This adds support for U32 filter by using an HW only feature called
Flexible RX Parser. This allow us to match any given packet field with a
pattern and accept/reject or even route the packet to a specific DMA
channel.
Right now we only support acception or rejection of frame and we only
support simple rules. Though, the Parser has the flexibility of jumping to
specific rules as an if condition so complex rules can be established.
This is only supported in GMAC5.10+.
The following commands can be used to test this code:
1) Setup an ingress qdisk:
# tc qdisc add dev eth0 handle ffff: ingress
2) Setup a filter (e.g. filter by IP):
# tc filter add dev eth0 parent ffff: protocol ip u32 match ip \
src 192.168.0.3 skip_sw action drop
In every tests performed we always used the "skip_sw" flag to make sure
only the RX Parser was involved.

When sending packets as fast as possible using "cangen -g 0 -i -x", the
HI-3110 occasionally latches the interrupt pin high on completion of a
packet, but doesn't set the TXCPLT bit in the INTF register. The INTF
register contains 0x00 as if no interrupt has occurred. Even waiting
for a few milliseconds after the interrupt doesn't help.
Work around this apparent erratum by instead checking the TXMTY bit in
the STATF register ("TX FIFO empty"). We know that we've queued up a
packet for transmission if priv->tx_len is nonzero. If the TX FIFO is
empty, transmission of that packet must have completed.
Note that this is congruent with our handling of received packets, which
likewise gleans from the STATF register whether a packet is waiting in
the RX FIFO, instead of looking at the INTF register.

hi3110_get_berr_counter() may run concurrently to the rest of the driver
but neglects to acquire the lock protecting access to the SPI device.
As a result, it and the rest of the driver may clobber each other's tx
and rx buffers.
We became aware of this issue because transmission of packets with
"cangen -g 0 -i -x" frequently hung. It turns out that agetty executes
->do_get_berr_counter every few seconds via the following call stack:
CPU: 2 PID: 1605 Comm: agetty
[<7f3f7500>] (hi3110_get_berr_counter [hi311x])
[<7f130204>] (can_fill_info [can_dev])

[<80661ec0>] (SyS_recvmsg)
[<80108b20>] (ret_fast_syscall+0x0/0x1c)
agetty listens to netlink messages in order to update the login prompt
when IP addresses change (if /etc/issue contains \4 or \6 escape codes):
https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/?id=e36deb6424e8
It's a useful feature, though it seems questionable that it causes CAN
bit error statistics to be queried.
Be that as it may, if hi3110_get_berr_counter() is invoked while a frame
is sent by hi3110_hw_tx(), bogus SPI transfers like the following may
occur:
=> 12 00 (hi3110_get_berr_counter() wanted to transmit
EC 00 to query the transmit error counter,
but the first byte was overwritten by
hi3110_hw_tx_frame())
=> EA 00 3E 80 01 FB (hi3110_hw_tx_frame() wanted to transmit a
frame, but the first byte was overwritten by
hi3110_get_berr_counter() because it wanted
to query the receive error counter)
This sequence hangs the transmission because the driver believes it has
sent a frame and waits for the interrupt signaling completion, but in
reality the chip has never sent away the frame since the commands it
received were malformed.
Fix by acquiring the SPI lock in hi3110_get_berr_counter().
I've scrutinized the entire driver for further unlocked SPI accesses but
found no others.

Some BPF capabilities carry no value, they simply indicate feature
is present. Our capability parsing loop will exit early if last
capability is zero-length because it's looking for more than 8 bytes
of data (8B is our TLV header length). Allow the last capability to
be zero-length.
This bug would lead to driver failing to probe with the following error
if the last capability FW advertises is zero-length:
nfp: BPF capabilities left after parsing, parsed:92 total length:100
nfp: invalid BPF capabilities at offset:92
Note the "parsed" and "length" values are 8 apart.

BPF has access to all internal FW datapath structures. Including
the structure containing RX queue selection. With little coordination
with the datapath we can let the offloaded BPF select the RX queue.
We just need a way to tell the datapath that queue selection has already
been done and it shouldn't overwrite it. Define a bit to tell datapath
BPF already selected a queue (QSEL_SET), if the selected queue is not
enabled (>= number of enabled queues) datapath will perform normal RSS.
BPF queue selection on the NIC can be used to replace standard

We have support for accelerating macvlan devices via the
.ndo_dfwd_add_station() netdev op. These accelerated macvlan MAC
addresses are stored in the l2_accel structure, separate from the
unicast or multicast address lists.
If a VLAN is added on top of the macvlan device by the stack, traffic
will not properly flow to the macvlan. This occurs because we fail to
setup the VLANs for l2_accel MAC addresses.
In the non-offloaded case the MAC address is added to the unicast
address list, and thus the normal setup for enabling VLANs works as
expected.
We also need to add VLANs marked from .ndo_vlan_rx_add_vid() into the
l2_accel MAC addresses. Otherwise, VLAN traffic will not properly be
received by the VLAN devices attached to the offloaded macvlan devices.
Fix this by adding necessary logic to setup VLANs not only for the
unicast and multicast addresses, but also the l2_accel list. We need
similar logic in dfwd_add_station, dfwd_del_station, fm10k_update_vid,
and fm10k_restore_rx_state.

While carrying energy detection(ED) tests, the chip will stop
transmission upon detecting an energy in the connected channel.
As a feedback, driver will stop dequeuing TX packets and due to
which wmm_tx_pending keep incremeting. Once wmm_tx_pending
reaches 100, driver calls netif_tx_stop_queue(). If TX ques is
not restarted within 5(watchdog_timeo) seconds, it will result in
TX timeout.
The ED test is carried out for one minute and the current
threshold of 100 is easily overcome by the traffic, cuasing TX
timeouts. To fix this increase the threshold to 400.

Add support for the BCM43364 chipset via an SDIO interface, as used in

The BCM43364 uses the same firmware as the BCM43430 (which is already

However, the SDIO_ID for the BCM43364 is 02D0:A9A4, giving it a MODALIAS
of sdio:c00v02D0dA9A4, which doesn't get recognised and hence doesn't

Since commit a92a08499b "r8169: improve runtime pm in general and
suspend unused ports" interfaces w/o link are runtime-suspended after
10s. On systems where drivers take longer to load this can lead to the
situation that the interface is runtime-suspended already when it's
initially brought up.
This shouldn't be a problem because rtl_open() resumes MAC/PHY.
However with at least one chip version the interface doesn't properly
come up, as reported here:
https://bugzilla.kernel.org/show_bug.cgi?id=199549
The vendor driver uses a delay to give certain chip versions some
time to resume before starting the PHY configuration. So let's do
the same. I don't know which chip versions may be affected,
therefore apply this delay always.
This patch was reported to fix the issue for RTL8168h.
I was able to reproduce the issue on an Asus H310I-Plus which also
uses a RTL8168h. Also in my case the patch fixed the issue.

When computing the bitrate using values read from an SFP module EEPROM,
we use the nominal BR plus BR,min and BR,max to determine the
boundaries. But in some cases BR,min and BR,max aren't provided, which
led the SFP code to end up having the nominal value for both the minimum
and maximum bitrate values. When using a passive cable, the nominal
value should be used as the maximum one, and there is no minimum one
so we should use 0.

The current code already forwards the VF MAC address to the PF, except
in one case. If the VF driver gets a valid MAC address from the firmware
during probe time, it will not forward the MAC address to the PF,
incorrectly assuming that the PF already knows the MAC address. This
causes "ip link show" to show zero VF MAC addresses for this case.
This assumption is not correct. Newer firmware remembers the VF MAC
address last used by the VF and provides it to the VF driver during
probe. So we need to always forward the VF MAC address to the PF.
The forwarded MAC address may now be the PF assigned MAC address and so we
need to make sure we approve it for this case.

A recent change to reduce delay granularity waiting for firmware
reponse has caused a regression. With a tighter delay loop,
the driver may see the beginning part of the response faster.
The original 5 usec delay to wait for the rest of the message
is not long enough and some messages are detected as invalid.
Increase the maximum wait time from 5 usec to 20 usec. Also, fix
the debug message that shows the total delay time for the response
when the message times out. With the new logic, the delay time
is not fixed per iteration of the loop, so we define a macro to
show the total delay time.

In commit 88462d2a78 ("can: flexcan: Remodel FlexCAN register r/w APIs
for big endian FlexCAN controllers.") the following logic was
implemented:
if the dt property "big-endian" is given or
the device is compatible to "fsl,p1010-flexcan":
use big-endian mode;
else
use little-endian mode;
This relies on commit d50f4630c2 ("arm: dts: Remove p1010-flexcan
compatible from imx series dts") which was applied a few commits later.
Without this commit (or an old device tree used for booting a new
kernel) the flexcan devices on i.MX25, i.MX28, i.MX35 and i.MX53 match
the 'the device is compatible to "fsl,p1010-flexcan"' test and so are
switched erroneously to big endian mode.
Instead of the check above put a quirk in devtype data and rely on
of_match_device yielding the most compatible match

bus-off is usually caused by hardware malfunction or configuration error

Increase the "bus-off" message's severity from netdev_dbg() to

A can interface going into bus-off is similar in severity to ethernet's

It is debatable whether the the "restarted" message should also be
changed to netdev_info() to make the interface state changes

`mf_mode' field indicates the multi-partitioning mode the device is
configured to. This method doesn't scale very well, adding a new MF mode
requires going over all the existing conditions, and deciding whether those
are needed for the new mode or not.
The patch defines a set of bit-fields for modes which are derived according
to the mode info shared by the MFW and all the configuration would be made
according to those. To add a new mode, there would be a single place where
we'll need to go and choose which bits apply and which don't.

Add support for the perf_event_output family of helpers.
The implementation on the NFP will not match the host code exactly.
The state of the host map and rings is unknown to the device, hence
device can't return errors when rings are not installed. The device
simply packs the data into a firmware notification message and sends
it over to the host, returning success to the program.
There is no notion of a host CPU on the device when packets are being
processed. Device will only offload programs which set BPF_F_CURRENT_CPU.
Still, if map index doesn't match CPU no error will be returned (see
above).
Dropped/lost firmware notification messages will not cause "lost
events" event on the perf ring, they are only visible via device
error counters.
Firmware notification messages may also get reordered in respect
to the packets which caused their generation.

For asynchronous events originating from the device, like perf event
output, we need to be able to make sure that objects being referred
to by the FW message are valid on the host. FW events can get queued
and reordered. Even if we had a FW message "barrier" we should still
protect ourselves from bogus FW output.
Add a reverse-mapping hash table and record in it all raw map pointers
FW may refer to. Only record neutral maps, i.e. perf event arrays.
These are currently the only objects FW can refer to. Use RCU protection
on the read side, update side is under RTNL.
Since program vs map destruction order is slightly painful for offload
simply take an extra reference on all the recorded maps to make sure
they don't disappear.

However, get_fixed_ipv6_csum() does a lot of redundant operations,
calling csum_partial() twice.
First csum_partial() computes the checksum of saddr and daddr,
put in @csum_pseudo_hdr. Undone later in the second csum_partial()
computed on whole ipv6 header.
Then nexthdr is added once, added a second time, then substracted.
payload_len is added once, then substracted.
