There is an assignment to *netdev that is that can potentially be null
but the null check is checking netdev and not *netdev as intended. Fix
this by adding in the missing * operator.

We found that with the latest mainline kernel (5.12.0-051200rc8) on
some KVM instances / bare-metal systems, the following tests will take
longer than the kselftest framework default timeout (45 seconds) to
run and thus got terminated with TIMEOUT error:
* xfrm_policy.sh - took about 2m20s
* pmtu.sh - took about 3m5s
* udpgso_bench.sh - took about 60s
Bump the timeout setting to 5 minutes to allow them have a chance to
finish.

mptcp: Compatibility with common msg flags
These patches from the MPTCP tree handle some of the msg flags that are
typically used with TCP, to make it easier to adapt userspace programs
for use with MPTCP.
Patches 1, 2, and 4 add support for MSG_ERRQUEUE (no-op for now),
MSG_TRUNC, and MSG_PEEK on the receive side.
Patch 3 ignores unsupported msg flags for send and receive.
Patch 5 adds a selftest for MSG_PEEK.

Currently mptcp_sendmsg() fails with EOPNOTSUPP if the
user-space provides some unsupported flag. That is unexpected
and may foul existing applications migrated to MPTCP, which
expect a different behavior.
Change the mentioned function to silently ignore the unsupported
flags except MSG_FASTOPEN. This is the only flags currently not
supported by MPTCP with user-space visible side-effects.

mptcp_recvmsg() currently silently ignores MSG_ERRQUEUE, returning
input data instead of error cmsg.
This change provides a dummy implementation for MSG_ERRQUEUE - always
returns no data. That is consistent with the current lack of a suitable

40GbE Intel Wired LAN Driver Updates 2021-04-23
This series contains updates to i40e and iavf drivers.
Aleksandr adds support for VIRTCHNL_VF_CAP_ADV_LINK_SPEED in i40e which
allows for reporting link speed to VF as a value instead of using an
enum; helper functions are created to remove repeated code.
Coiby Xu reduces memory use of i40e when using kdump by reducing Tx, Rx,
and admin queue to minimum values. Current use causes failure of kdump.
Stefan Assmann removes duplicated free calls in iavf.
Haiyue cleans up a loop to return directly when if the value is found
and changes some magic numbers to defines for better maintainability
in iavf.

selftests: mlxsw: Fixes
This patch set carries fixes to selftest issues that we have hit in our
nightly regression run. Almost all are in mlxsw selftests, though one is in
a generic forwarding selftest.
- In patch #1, in an ERSPAN test, install an FDB entry as static instead of
(implicitly) as local.
- In the mlxsw resource-scale test, an if statement overrides the value of
$?, which is supposed to contain the result of the test. As a result, the
resource scale test can spuriously pass.
In patches #2 and #3, remove the if statements to fix the issue in,
respectively, port_scale test and tc_flower_scale tests.
- Again in the mlxsw resource-scale test, when more then one sub-test is
run, a successful sub-test overrides any previous failures. This causes a
spurious pass of the overall test. This is fixed in patch #4.
- In patch #5, increase a tolerance in a mlxsw-specific RED backlog test.
This test is very noisy, due to rounding errors and the unpredictability
of software traffic generation. By bumping the tolerance from 5 % to 10,
get the failure rate to zero. This shouldn't impact the accuracy,
mistakes in backlog configuration (e.g. due to wrong cell size) are
likely to cause a much larger discrepancy.
- In patch #6, fix mausezahn invocation in the mlxsw ERSPAN scale
test. The test failed because of the wrong invocation.
====================

The mirror_gre_scale test creates as many ERSPAN sessions as the underlying
chip supports, and tests that they all work. In order to determine that it
issues a stream of ICMP packets and checks if they are mirrored as
expected.
However, the mausezahn invocation missed the -6 flag to identify the use of
IPv6 protocol, and was sending ICMP messages over IPv6, as opposed to
ICMP6. It also didn't pass an explicit source IP address, which apparently
worked at some point in the past, but does not anymore.
To fix these issues, extend the function mirror_test() in mirror_lib by
detecting the IPv6 protocol addresses, and using a different ICMP scheme.
Fix __mirror_gre_test() in the selftest itself to pass a source IP address.

The intention behind this test is to make sure that qdisc limit is
correctly projected to the HW. However, first, due to rounding in the
qdisc, and then in the driver, the number cannot actually be accurate. And
second, the approach to testing this is to oversubscribe the port with
traffic generated on the same switch. The actual backlog size therefore
fluctuates.
In practice, this test proved to be noisier than the rest, and spuriously
fails every now and then. Increase the tolerance to 10 % to avoid these
issues.

Currently, the resource scale test checks a few cases, when the error code
resets between the cases. So for example, if one case fails and the
consecutive case passes, the error code eventually will fit the last test
and will be 0.
Save a new return code that will hold the 'or' return codes of all the
cases, so the final return code will consider all the cases.

The FDB roaming test installs a destination MAC address on the wrong
interface of an FDB database and tests whether the mirroring fails, because
packets are sent to the wrong port. The test by mistake installs the FDB
entry as local. This worked previously, because drivers were notified of
local FDB entries in the same way as of static entries. However that has
been fixed in the commit 6ab4c3117aec ("net: bridge: don't notify switchdev
for local FDB addresses"), and local entries are not notified anymore. As a
result, the HW is not reconfigured for the FDB roam, and mirroring keeps
working, failing the test.
To fix the issue, mark the FDB entry as static.

The previous patch to support PTP Sync packet one-step timestamping
described one-step timestamping packet handling logic as below in
commit message:
- Trasmit packet immediately if no other one in transfer, or queue to
skb queue if there is already one in transfer.
The test_and_set_bit_lock() is used here to lock and check state.
- Start a work when complete transfer on hardware, to release the bit
lock and to send one skb in skb queue if has.
There was not problem of the description, but there was a mistake in
implementation. The locking/test_and_set_bit_lock() should be put in
enetc_start_xmit() which may be called by worker, rather than in
enetc_xmit(). Otherwise, the worker calling enetc_start_xmit() after
bit lock released is not able to lock again for transfer.
