When exporting and running a subset of selftests via kselftest, files from
parts of the source tree which were not exported are not available. A few
tests are trying to source such files. Address the problem by using
symlinks.
The problem can be reproduced by running:
make -C tools/testing/selftests gen_tar TARGETS="drivers/net/bonding"
[... extract archive ...]
./run_kselftest.sh
or:
make kselftest KBUILD_OUTPUT=/tmp/kselftests TARGETS="drivers/net/bonding"

We can make the phc2sys helper not only synchronize a PHC to
CLOCK_REALTIME, which is what it currently does, but also CLOCK_REALTIME
to a PHC, which is going to be needed in distributed TSN tests.
Instead of making the complexity of the arguments passed to
phc2sys_start() explode, we can let it figure out the sync direction
automatically, based on ptp4l's port states.
Towards that goal, pass just the path to the desired ptp4l instance's
UNIX domain socket, and remove the $if_name argument (from which it
derives the PHC). Also adapt the one caller from the ocelot psfp.sh
test. In the case of psfp.sh, phc2sys_start is able to properly figure
out that CLOCK_REALTIME is the source clock and swp1's PHC is the
destination, because of the way in which ptp4l_start for the
UDS_ADDRESS_SWP1 was called: with slave_only=false, so it will always
win the BMCA and always become the sync master between itself and $h1.

It looks like this test has been accidentally dropped when resolving
conflicts in this Makefile.
Most probably because there were 3 different patches modifying this file
in parallel:
commit 152e8ec77640 ("selftests/bonding: add a test for bonding lladdr target")
commit bbb774d921e2 ("net: Add tests for bonding and team address list management")
commit 2ffd57327ff1 ("selftests: bonding: cause oops in bond_rr_gen_slave_id")
The first one was applied in 'net-next' while the two other ones were
recently applied in the 'net' tree.
But that's alright, easy to fix by re-adding the missing one!

Add an equivalent test to qos_burst, the test's purpose is same, but the
new test uses simpler topology and does not require forcing low speed.
In addition, it can be run Spectrum-2 and not only Spectrum-3+. The idea
is to use a shaper in order to limit the traffic and create congestion.
qos_burst test uses small pool, sends many small packets, and verify that
packets are not dropped, which means that many descriptors can be handled.
This test should check the change that commit c864769add96
("mlxsw: Configure descriptor buffers") pushed.
Instead, the new test tries to use more than 85% of maximum supported
descriptors. The idea is to use big pool (as much as the ASIC supports),
such that the pool size does not limit the traffic, then send many small
packets, which means that many descriptors are used, and check how many
packets the switch can handle.
The usage of shaper allows to run the test in all ASICs, regardless of
the CPU abilities, as it is able to create the congestion with low rate
of packets.

QOS tests create congestion and verify the switch behavior. To create
congestion, they need to have more traffic than the port can handle, so
some of them force 1Gbps speed.
The tests assume that 1Gbps speed is supported, otherwise, they will fail.
Spectrum-4 ASIC will not support this speed in all ports, so to be able
to run the tests there, some adjustments are required. Use shapers to limit
the traffic instead of forcing speed. Note that for several ports, the
speed configuration is just for autoneg issues, so shaper is not needed
instead.
The tests already use ETS qdisc as a root and RED qdiscs as children. Add
a new TBF shaper to limit the rate of traffic, and use it as a root qdisc,
then save the previous hierarchy of qdiscs under the new TBF root.
In some ASICs, the shapers do not limit the traffic as accurately as
forcing speed. To make the tests stable, allow the backlog size to be up to
+-10% of the threshold. The aim of the tests is to make sure that with
backlog << threshold, there are no drops, and that packets are dropped
somewhere in vicinity of the configured threshold.

After routing, the device always consults a table that determines the
packet's egress VID based on {egress RIF, egress local port}. In the
unified bridge model, it is up to software to maintain this table via
REIV register.
The table needs to be updated in the following flows:
1. When a RIF is set on a FID, for each FID's {Port, VID} mapping, a new
{RIF, Port}->VID mapping should be created.
2. When a {Port, VID} is mapped to a FID and the FID already has a RIF,
a new {RIF, Port}->VID mapping should be created.
Add a test to verify that packets get the correct VID after routing,
regardless of the order of the configuration.

This tests creates as many RIFs as possible, ideally more than there can be
RIF counters (though that is currently only possible on Spectrum-1). It
then tries to enable L3 HW stats on each of the RIFs. It also contains the
traffic test, which tries to run traffic through a log2 of those counters
and checks that the traffic is shown in the counter values.
Like with tc_flower traffic test, take a log2 subset of rules. The logic
behind picking log2 rules is that then every bit of the instantiated item's
number is exercised. This should catch issues whether they happen at the
high end, low end, or somewhere in between.

The scale tests are verifying behavior of mlxsw when number of instances of
some resource reaches the ASIC capacity. The number of instances is
referred to as "target" number.
No scale tests so far needed to know this target number to clean up. E.g.
the tc_flower simply removes the clsact qdisc that all the tested filters
are hooked onto, and that takes care of collecting all the filters.
However, for the RIF counter test, which is being added in a future patch,
VLAN netdevices are created. These are created as part of the test, but of
course the cleanup needs to undo them again. For that it needs to know how
many there were. To support this usage, pass the target number to the
cleanup callback.

The scale tests are currently testing two things: that some number of
instances of a given resource can actually be created; and that when an
attempt is made to create more than the supported amount, the failures are
noted and handled gracefully.
Sometimes the scale test depends on more than one resource. In particular,
a following patch will add a RIF counter scale test, which depends on the
number of RIF counters that can be bound, and also on the number of RIFs
that can be created.
When the test is limited by the auxiliary resource and not by the primary
one, there's no point trying to run the overflow test, because it would be
testing exhaustion of the wrong resource.
To support this use case, when the $test_get_target yields 0, skip the test
instead.

The scale tests are currently testing two things: that some number of
instances of a given resource can actually be created; and that when an
attempt is made to create more than the supported amount, the failures are
noted and handled gracefully.
However the ability to allocate the resource does not mean that the
resource actually works when passing traffic. For that, make it possible
for a given scale to also test traffic.
Traffic test is only run on the positive leg of the scale test (no point
trying to pass traffic when the expected outcome is that the resource will
not be allocated). Traffic tests are opt-in, if a given test does not
expose it, it is not run.
To this end, delay the test cleanup until after the traffic test is run.

The scale of each resource is tested in the following manner:
1. The scale target is queried.
2. The test setup is prepared.
3. The test is invoked.
In some cases, the occupancy of a resource changes as part of the second
step, requiring the test to return a scale target that takes this change
into account.
Make this more robust by re-querying the scale target after the second
step.
Another possible solution is to swap the first and second steps, but
when a test needs to be skipped (i.e., scale target is zero), the setup
would have been in vain.

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.

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.

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.

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.

This adds an initial subset of forwarding selftests which I considered
to be relevant for DSA drivers, along with a forwarding.config that
makes it easier to run them (disables veth pair creation, makes sure MAC
addresses are unique and stable).
The intention is to request driver writers to run these selftests during
review and make sure that the tests pass, or at least that the problems
are known.

Extend tcpdump_start() & C:o to handle multiple instances. Useful when
observing bridge operation, e.g., unicast learning/flooding, and any
case of multicast distribution (to these ports but not that one ...).
This means the interface argument is now a mandatory argument to all
tcpdump_*() functions, hence the changes to the ocelot flower test.

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.
