4ea1396a8b selftests: ocelot: tc_flower_chains: reorder interfaces
Use the standard interface order h1, swp1, swp2, h2 that is used by the
forwarding selftest framework. The previous order was confusing even
with the ASCII drawing. That isn't needed anymore.

This also drops the fixed MAC addresses and uses STABLE_MAC_ADDRS, which
ensures the MAC addresses are unique.

93196ef911 selftests: ocelot: tc_flower_chains: use conventional interface names
This is a robotic rename as follows:

eth0 -> swp1
eth1 -> swp2
eth2 -> h2
eth3 -> h1

This brings the selftest more in line with the other forwarding
selftests, where h1 is connected to swp1, and h2 to swp2.

7ba106fcd4 selftests: netdevsim: Increase sleep time in hw_stats_l3.sh test
hw_stats_l3.sh test is failing often for l3 stats shows less than 20
packets after 2 seconds sleep.

This is happening since there is a race between the 2 seconds sleep and
the netdevsim actually delivering the packets.

Increase the sleep time so the packets will be delivered successfully on
time.

5a7c5f70c7 selftests: ocelot: tc_flower_chains: specify conform-exceed action for policer
As discussed here with Ido Schimmel:
https://patchwork.kernel.org/project/netdevbpf/patch/20220224102908.5255-2-jianbol@nvidia.com/

the default conform-exceed action is "reclassify", for a reason we don't
really understand.

The point is that hardware can't offload that police action, so not
specifying "conform-exceed" was always wrong, even though the command
used to work in hardware (but not in software) until the kernel started
adding validation for it.

Fix the command used by the selftest by making the policer drop on
exceed, and pass the packet to the next action (goto) on conform.

18d2c710e5 selftests: mlxsw: bail_on_lldpad before installing the cleanup trap
A number of mlxsw-specific QoS tests use manual QoS DCB management. As
such, they need to make sure lldpad is not running, because it would
override the configuration the test has applied using other tools. To that
end, these selftests invoke the bail_on_lldpad() helper, which terminates
the selftest if th lldpad is running.

Some of these tests however first install the bash exit trap, which invokes
a cleanup() at the test exit. If bail_on_lldpad() has terminated the script
even before the setup part was run, the cleanup part will be very confused.

Therefore make sure bail_on_lldpad() is invoked before the cleanup is
registered.

While there are still edge cases where the user terminates the script
before the setup was fully done, this takes care of a common situation
where the cleanup would be invoked in an inconsistent state.

954f46d2f0 selftests: forwarding: add Per-Stream Filtering and Policing test for Ocelot
The Felix VSC9959 switch in NXP LS1028A supports the tc-gate action
which enforced time-based access control per stream. A stream as seen by
this switch is identified by {MAC DA, VID}.

We use the standard forwarding selftest topology with 2 host interfaces
and 2 switch interfaces. The host ports must require timestamping non-IP
packets and supporting tc-etf offload, for isochron to work. The
isochron program monitors network sync status (ptp4l, phc2sys) and
deterministically transmits packets to the switch such that the tc-gate
action either (a) always accepts them based on its schedule, or
(b) always drops them.

I tried to keep as much of the logic that isn't specific to the NXP
LS1028A in a new tsn_lib.sh, for future reuse. This covers
synchronization using ptp4l and phc2sys, and isochron.

The cycle-time chosen for this selftest isn't particularly impressive
(and the focus is the functionality of the switch), but I didn't really
know what to do better, considering that it will mostly be run during
debugging sessions, various kernel bloatware would be enabled, like
lockdep, KASAN, etc, and we certainly can't run any races with those on.

I tried to look through the kselftest framework for other real time
applications and didn't really find any, so I'm not sure how better to
prepare the environment in case we want to go for a lower cycle time.
At the moment, the only thing the selftest is ensuring is that dynamic
frequency scaling is disabled on the CPU that isochron runs on. It would
probably be useful to have a blacklist of kernel config options (checked
through zcat /proc/config.gz) and some cyclictest scripts to run
beforehand, but I saw none of those.

5e6242151d selftests: mlxsw: vxlan_flooding_ipv6: Prevent flooding of unwanted packets
The test verifies that packets are correctly flooded by the bridge and
the VXLAN device by matching on the encapsulated packets at the other
end. However, if packets other than those generated by the test also
ingress the bridge (e.g., MLD packets), they will be flooded as well and
interfere with the expected count.

Make the test more robust by making sure that only the packets generated
by the test can ingress the bridge. Drop all the rest using tc filters
on the egress of 'br0' and 'h1'.

In the software data path, the problem can be solved by matching on the
inner destination MAC or dropping unwanted packets at the egress of the
VXLAN device, but this is not currently supported by mlxsw.

Currently, there is a test case to verify that VxLAN with IPv6 underlay
is forbidden.

Remove this test case as support for VxLAN with IPv6 underlay was added

Add a test case to cover the bug fixed by the previous patch.

Edit the MAC address of one netdev so that it matches the MAC address of
the second netdev. Verify that the two MAC profiles were consolidated by
testing that the MAC profiles occupancy decreased by one.

535ac9a5fb selftests: mlxsw: Use permanent neighbours instead of reachable ones
The nexthop objects tests configure dummy reachable neighbours so that
the nexthops will have a MAC address and be programmed to the device.

Since these are dummy reachable neighbours, they can be transitioned by
the kernel to a failed state if they are around for too long. This can
happen, for example, if the "TIMEOUT" variable is configured with a too
high value.

Make the tests more robust by configuring the neighbours as permanent,
so that the tests do not depend on the configured timeout value.

b8bfafe434 selftests: mlxsw: Add helpers for skipping selftests
A number of mlxsw-specific selftests currently detect whether they are run
on a compatible machine, and bail out silently when not. These tests are
however done in a somewhat impenetrable manner by directly comparing PCI
IDs against a blacklist or a whitelist, and bailing out silently if the
machine is not compatible.

Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying
the supported machines in a human-readable manner. If the current machine
is incompatible, the helper emits a SKIP message and returns an error code,
based on which the caller can gracefully bail out in a suitable way. This
allows a more readable conditions such as:

	mlxsw_only_on_spectrum 2+ || return

Convert all existing open-coded guards to the new helper. Also add two new
guards to do_mark_test() and do_drop_test(), which are supported only on
Spectrum-2+, but the corresponding check was not there.

eccd0a80dc selftests: net: dsa: add a stress test for unlocked FDB operations
This test is a bit strange in that it is perhaps more manual than
others: it does not transmit a clear OK/FAIL verdict, because user space
does not have synchronous feedback from the kernel. If a hardware access
fails, it is in deferred context.

Nonetheless, on sja1105 I have used it successfully to find and solve a
concurrency issue, so it can be used as a starting point for other
driver maintainers too.
