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
datapath RSS with fully programmable BPF/XDP RSS.

We don't actually need to check if the host mbx is ready when queuing
MAC requests, because these are not handled by a special queue which
queues up requests until the mailbox is capable of handling them.
Pull these requests outside the fm10k_host_mbx_ready() check, as it is

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
e.g. the Murata 1FX module.
The BCM43364 uses the same firmware as the BCM43430 (which is already
included), the only difference is the omission of Bluetooth.
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
load the brcmfmac module. Adding the 'A9A4' ID in the appropriate place
triggers the brcmfmac driver to load, and then correctly use the
firmware file 'brcmfmac43430-sdio.bin'.

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
(baud rate mismatch) and causes a complete loss of communication.
Increase the "bus-off" message's severity from netdev_dbg() to
netdev_info() to make it visible to the user.
A can interface going into bus-off is similar in severity to ethernet's
"Link is Down" message, which is also printed at info level.
It is debatable whether the the "restarted" message should also be
changed to netdev_info() to make the interface state changes
comprehensible from the kernel log. I have chosen to keep the
"restarted" message at dbg for now as the "bus-off" message should be
enough for the user to notice and investigate the problem.

The patch defines a set of bit-fields for modes which are derived according

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

error counters.

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.

Currently, skb->len and skb->data_len are set to the page size, not
the packet size. This causes the frame check sequence to not be
located at the "end" of the packet resulting in ethernet frame check
errors. The driver does work currently, but stricter kernel facing
networking solutions like OpenVSwitch will drop these packets as
invalid.
These changes set the packet size correctly so that these errors no
longer occur. The length does not include the frame check sequence, so
that subtraction was removed.

While trying to support CHECKSUM_COMPLETE for IPV6 fragments,
I had to experiments various hacks in get_fixed_ipv6_csum().
I must admit I could not find how to implement this :/
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.
Really all this can be reduced to two add_csum(), to add back 6 bytes
that were removed by mlx4 when providing hw_checksum in RX descriptor.

In dual_mac mode packets arrived on one port should not be forwarded by
switch hw to another port. Only Linux Host can forward packets between
ports. The below test case (reported in [1]) shows that packet arrived on
one port can be leaked to anoter (reproducible with dual port evms):
- connect port 1 (eth0) to linux Host 0 and run tcpdump or Wireshark
- connect port 2 (eth1) to linux Host 1 with vlan 1 configured
- ping <IPx> from Host 1 through vlan 1 interface.
ARP packets will be seen on Host 0.
Issue happens because dual_mac mode is implemnted using two vlans: 1 (Port
1+Port 0) and 2 (Port 2+Port 0), so there are vlan records created for for
each vlan. By default, the ALE will find valid vlan record in its table
when vlan 1 tagged packet arrived on Port 2 and so forwards packet to all
ports which are vlan 1 members (like Port.
To avoid such behaviorr the ALE VLAN ID Ingress Check need to be enabled
for each external CPSW port (ALE_PORTCTLn.VID_INGRESS_CHECK) so ALE will
drop ingress packets if Rx port is not VLAN member.

In Innova TLS, TLS contexts are added or deleted

40GbE Intel Wired LAN Driver Updates 2018-04-30
This series contains updates to i40e and i40evf only.
Jia-Ju Bai replaces an instance of GFP_ATOMIC to GFP_KERNEL, since
i40evf is not in atomic context when i40evf_add_vlan() is called.
Jake cleans up function header comments to ensure that the function
parameter comments actually match the function parameters. Fixed a
possible overflow error in the PTP clock code. Fixed warnings regarding
restricted __be32 type usage.
Mariusz fixes the reading of the LLDP configuration, which moves from
using relative values to calculating the absolute address.
Jakub adds a check for 10G LR mode for i40e.
Paweł fixes an issue, where changing the MTU would turn on TSO, GSO and
GRO.
Alex fixes a couple of issues with the UDP tunnel filter configuration.
First being that the tunnels did not have mutual exclusion in place to
prevent a race condition between a user request to add/remove a port and
an update. The second issue was we were deleting filters that were not
associated with the actual filter we wanted to delete.
Harshitha ensures that the queue map sent by the VF is taken into
account when enabling/disabling queues in the VF VSI.

When handling mirroring to a gretap or ip6gretap netdevice in mlxsw, the
underlay address (i.e. the remote address of the tunnel) may be routed
to a bridge.
In that case, look up the resolved neighbor Ethernet address in that
bridge's FDB. Then configure the offload to direct the mirrored traffic
to that port, possibly with tagging.

Changes to switchdev artifact can make a SPAN entry offloadable or
unoffloadable. To that end:
- Listen to SWITCHDEV_FDB_*_TO_BRIDGE notifications in addition to
the *_TO_DEVICE ones, to catch whatever activity is sent to the
bridge (likely by mlxsw itself).
On each FDB notification, respin SPAN to reconcile it with the FDB
changes.
- Also respin on switchdev port attribute changes (which currently
covers changes to STP state of ports) and port object additions and

When operating at 1GbE, the base incval for the PTP clock is so large
that multiplying it by numbers close to the max_adj can overflow the
u64.
Rather than attempting to limit the max_adj to a value small enough to
avoid overflow, instead calculate the incvalue adjustment based on the
40GbE incvalue, and then multiply that by the scaling factor for the
link speed.
This sacrifices a small amount of precision in the adjustment but we
avoid erratic behavior of the clock due to the overflow caused if ppb is
very near the maximum adjustment.

This fixes at least 2 issues I have found with the UDP tunnel filter
configuration.
The first issue is the fact that the tunnels didn't have any sort of mutual
exclusion in place to prevent an update from racing with a user request to
add/remove a port. As such you could request to add and remove a port
before the port update code had a chance to respond which would result in a
very confusing result. To address it I have added 2 changes. First I added
the RTNL mutex wrapper around our updating of the pending, port, and
filter_index bits. Second I added logic so that we cannot use a port that
has a pending deletion since we need to free the space in hardware before
we can allow software to reuse it.
The second issue addressed is the fact that we were not recording the
actual filter index provided to us by the admin queue. As a result we were
deleting filters that were not associated with the actual filter we wanted
to delete. To fix that I added a filter_index member to the UDP port
tracking structure.

After commit c59530d0d5 ("net: Move PHY statistics code into PHY
library helpers") we made net/core/ethtool.c reference symbols which are
part of the library which can be modular. David introduced a temporary
fix with 1ecd6e8ad9 ("phy: Temporary build fix after phylib changes.")
which would prevent such modularity.
This is not desireable of course, so instead, just inline the functions
into include/linux/phy.h to keep both options available.

Initially, the MQPRIO TCs are mapped 1:1 directly to the hardware
queues. Some of these hardware queues are configured to be lossless.
When PFC is enabled on one of more TCs, we now need to remap the
TCs that have PFC enabled to the lossless hardware queues.
After remapping, we need to close and open the NIC for the new
mapping to take effect. We also need to reprogram all ETS parameters.

The current driver maps MQPRIO traffic classes directly 1:1 to the
internal hardware queues (TC0 maps to hardware queue 0, etc). This
direct mapping requires the internal hardware queues to be reconfigured
from lossless to lossy and vice versa when necessary. This
involves reconfiguring internal buffer thresholds which is
disruptive and not always reliable.
Implement a new scheme to map TCs to internal hardware queues by
matching up their PFC requirements. This will eliminate the need
to reconfigure a hardware queue internal buffers at run time. After
remapping, the NIC is closed and opened for the new TC to hardware
queues to take effect.
This patch only adds the basic mapping logic.

While adding the DSA notifier, we will be sending DSA notifications with
info->master that is going to point to a particular net_device instance.
Our logic in bcm_sysport_map_queues() correctly disambiguates net_device
instances that are not covered by our own driver, but it will not make
sure that info->master points to a particular driver instance that we
are interested in. In a system where e.g: two or more SYSTEMPORT
instances are registered, this would lead in programming two or more
times the queue mapping, completely messing with the logic which does
the queue/port allocation and tracking.
Fix this by looking at the notifier_block pointer which is unique per
instance and allows us to go back to our driver private structure, and
in turn to the backing net_device instance.

pull-request: bpf-next 2018-04-27
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Add extensive BPF helper description into include/uapi/linux/bpf.h
and a new script bpf_helpers_doc.py which allows for generating a
man page out of it. Thus, every helper in BPF now comes with proper
function signature, detailed description and return code explanation,
from Quentin.
2) Migrate the BPF collect metadata tunnel tests from BPF samples over
to the BPF selftests and further extend them with v6 vxlan, geneve
and ipip tests, simplify the ipip tests, improve documentation and
convert to bpf_ntoh*() / bpf_hton*() api, from William.
3) Currently, helpers that expect ARG_PTR_TO_MAP_{KEY,VALUE} can only
access stack and packet memory. Extend this to allow such helpers
to also use map values, which enabled use cases where value from
a first lookup can be directly used as a key for a second lookup,
from Paul.
4) Add a new helper bpf_skb_get_xfrm_state() for tc BPF programs in
order to retrieve XFRM state information containing SPI, peer
address and reqid values, from Eyal.
5) Various optimizations in nfp driver's BPF JIT in order to turn ADD
and SUB instructions with negative immediate into the opposite
operation with a positive immediate such that nfp can better fit
small immediates into instructions. Savings in instruction count
up to 4% have been observed, from Jakub.
6) Add the BPF prog's gpl_compatible flag to struct bpf_prog_info
and add support for dumping this through bpftool, from Jiri.
7) Move the BPF sockmap samples over into BPF selftests instead since
sockmap was rather a series of tests than sample anyway and this way
this can be run from automated bots, from John.
8) Follow-up fix for bpf_adjust_tail() helper in order to make it work
with generic XDP, from Nikita.
9) Some follow-up cleanups to BTF, namely, removing unused defines from
BTF uapi header and renaming 'name' struct btf_* members into name_off
to make it more clear they are offsets into string section, from Martin.
10) Remove test_sock_addr from TEST_GEN_PROGS in BPF selftests since
not run directly but invoked from test_sock_addr.sh, from Yonghong.
11) Remove redundant ret assignment in sample BPF loader, from Wang.
12) Add couple of missing files to BPF selftest's gitignore, from Anders.
There are two trivial merge conflicts while pulling:
1) Remove samples/sockmap/Makefile since all sockmap tests have been
moved to selftests.
2) Add both hunks from tools/testing/selftests/bpf/.gitignore to the
file since git should ignore all of them.

If we fail to to grab NIC access because the device is not responding
(i.e. CSR_GP_CNTRL returns 0xFFFFFFFF), remove the device from the PCI
bus, to avoid any further damage, and to let the user space rescan.
In order to inform the userspace that a rescan is needed, we send a
kobject uevent with "INACCESSIBLE".
This functionality is disabled by default, but can be enabled via a
new module parameter called "remove_when_gone". In the future we may
change this module parameter to include 3 modes instead: do nothing;
auto-rescan or; send uevent.

1GbE Intel Wired LAN Driver Updates 2018-04-25
This series enables some ethtool and tc-flower filters to be offloaded
to igb-based network controllers. This is useful when the system
configuration wants to steer kinds of traffic to a specific hardware
queue for i210 devices only.
The first two patch in the series are bug fixes.
The basis of this series is to export the internal API used to
configure address filters, so they can be used by ethtool, and
extending the functionality so an source address can be handled.
Then, we enable the tc-flower offloading implementation to re-use the
same infrastructure as ethtool, and storing them in the per-adapter
"nfc" (Network Filter Config?) list. But for consistency, for
destructive access they are separated, i.e. an filter added by
tc-flower can only be removed by tc-flower, but ethtool can read them
all.
Only support for VLAN Prio, Source and Destination MAC Address, and
Ethertype is enabled for now.

10GbE Intel Wired LAN Driver Updates 2018-04-25
This series represents yet another phase of the macvlan cleanup Alex has
been working on.
The main goal of these changes is to make it so that we only support
offloading what we can actually offload and we don't break any existing
functionality. So for example we were claiming to advertise source mode
macvlan and we were doing nothing of the sort, so support for that has been
dropped.
The biggest change with this set is that broadcast/multicast replication is
no longer being supported in software. Alex dropped it as it leads to
scaling issues when a broadcast frame has to be replicated up to 64 times.
Beyond that this set goes through and optimized the time needed to bring up
and tear down the macvlan interfaces on ixgbe and provides a clean way for
us to disable the macvlan offload when needed.

This allows filters added by tc-flower and specifying MAC addresses,
Ethernet types, and the VLAN priority field, to be offloaded to the
controller.
This reuses most of the infrastructure used by ethtool, but clsflower
filters are kept in a separated list, so they are invisible to
ethtool.
To setup clsflower offloading:
$ tc qdisc replace dev eth0 handle 100: parent root mqprio \
num_tc 3 map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \
queues 1@0 1@1 2@2 hw 0
(clsflower offloading depends on the netword driver to be configured
with multiple traffic classes, we use mqprio's 'num_tc' parameter to
set it to 3)
$ tc qdisc add dev eth0 ingress
Examples of filters:
$ tc filter add dev eth0 parent ffff: flower \
dst_mac aa:aa:aa:aa:aa:aa \
hw_tc 2 skip_sw
(just a simple filter filtering for the destination MAC address and
steering that traffic to queue 2)
$ tc filter add dev enp2s0 parent ffff: proto 0x22f0 flower \
src_mac cc:cc:cc:cc:cc:cc \
hw_tc 1 skip_sw
(as the i210 doesn't support steering traffic based on the source
address alone, we need to use another steering traffic, in this case
we are using the ethernet type (0x22f0) to steer traffic to queue 1)

This adds the capability of configuring the queue steering of arriving
packets based on their source and destination MAC addresses.
Source address steering (i.e. driving traffic to a specific queue),
for the i210, does not work, but filtering does (i.e. accepting
traffic based on the source address). So, trying to add a filter
specifying only a source address will be an error.
In practical terms this adds support for the following use cases,
characterized by these examples:
$ ethtool -N eth0 flow-type ether dst aa:aa:aa:aa:aa:aa action 0
(this will direct packets with destination address "aa:aa:aa:aa:aa:aa"
to the RX queue 0)
$ ethtool -N eth0 flow-type ether src 44:44:44:44:44:44 \

Users expect that when adding a steering filter for the local MAC
address, that all the traffic directed to that address will go to some
queue.
Currently, it's not possible to configure entries in the "in use"
state, which is the normal state of the local MAC address entry (it is
the default), this patch allows to override the steering configuration
of "in use" entries, if the filter to be added match the address and
address type (source or destination) of an existing entry.
There is a bit of a special handling for entries referring to the

On the RAH registers there are semantic differences on the meaning of
the "queue" parameter for traffic steering depending on the controller
model: there is the 82575 meaning, which "queue" means a RX Hardware
Queue, and the i350 meaning, where it is a reception pool.
The previous behaviour was having no effect for i210 based controllers
because the QSEL bit of the RAH register wasn't being set.
This patch separates the condition in discrete cases, so the different
handling is clearer.

The original implementation for macvlan offload has us performing a full
port reset every time we added a new macvlan. This shouldn't be necessary
and can be avoided with a few behavior changes.
This patches updates the logic for the queues so that we have essentially 3
possible configurations for macvlan offload. They consist of 15 macvlans
with 4 queues per macvlan, 31 macvlans with 2 queues per macvlan, and 63
macvlans with 1 queue per macvlan. As macvlans are added you will encounter
up to 3 total resets if you add all the way up to 63, and after that the
device will stay in the mode supporting up to 63 macvlans until the L2FW
flag is cleared.

This change makes it so that we use a software path for packets that are
going to be locally switched between two macvlan interfaces on the same
device. In addition we resort to software replication of broadcast and
multicast packets instead of offloading that to hardware.
The general idea is that using the device for east/west traffic local to
the system is extremely inefficient. We can only support up to whatever the
PCIe limit is for any given device so this caps us at somewhere around 20G
for devices supported by ixgbe. This is compounded even further when you
take broadcast and multicast into account as a single 10G port can come to
a crawl as a packet is replicated up to 60+ times in some cases. In order
to get away from that I am implementing changes so that we handle
broadcast/multicast replication and east/west local traffic all in
software.
