Test that the bonding and team drivers clean up an underlying device's
address lists (dev->uc, dev->mc) when the aggregated device is deleted.
Test addition and removal of the LACPDU multicast address on underlying
devices by the bonding driver.
v2:
* add lag_lib.sh to TEST_FILES
v3:
* extend bond_listen_lacpdu_multicast test to init_state up and down cases
* remove some superfluous shell syntax and 'set dev ... up' commands

This has been validated on the Ocelot/Felix switch family (NXP LS1028A)
and should be relevant to any switch driver that offloads the tc-flower
and/or tc-matchall actions trap, drop, accept, mirred, for which DSA has
operations.

This creates a test collection in drivers/net/bonding for bonding
specific kernel selftests.
The first test is a reproducer that provisions a bond and given the
specific order in how the ip-link(8) commands are issued the bond never
transmits an LACPDU frame on any of its slaves.

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.

Before layer 2 forwarding, the device classifies an incoming packet to a
FID. After classification, the FID is known, but also all the attributes of
the FID, such as the router interface (RIF) via which a packet that needs
to be routed will ingress the router block.
For VXLAN decapsulation, the FID classification is done according to the
VNI. When a RIF is added on top of a FID, the existing VNI->FID mapping
should be updated by the software with the new RIF. In addition, when a new
mapping is added for FID which already has a RIF, the correct RIF should
be used for it.
Add a test to verify that packets can be routed after decapsulation which
is done after VNI->FID classification, regardless of the order of the

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.

The Kconfig S390_UV_UAPI must be selected and the Ultravisor facility
must be available. The test can be executed by non-root, however, the
uvdevice special file /dev/uv must be accessible for reading and

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.
