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.

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

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.

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.

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

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.

The test runs several test cases and is supposed to return an error in
case at least one of them failed.
Currently, the check of the return value of each test case is in the
wrong place, which can result in the wrong return value. For example:
# TESTS='tc_police' ./resource_scale.sh
TEST: 'tc_police' [default] 968 [FAIL]
tc police offload count failed
Error: mlxsw_spectrum: Failed to allocate policer index.
We have an error talking to the kernel
Command failed /tmp/tmp.i7Oc5HwmXY:969
TEST: 'tc_police' [default] overflow 969 [ OK ]
...
TEST: 'tc_police' [ipv4_max] overflow 969 [ OK ]
$ echo $?
0
Fix this by moving the check to be done after each test case.

The test adds tc filters and checks how many of them were offloaded by
grepping for 'in_hw'.
iproute2 commit f4cd4f127047 ("tc: add skip_hw and skip_sw to control
action offload") added offload indication to tc actions, producing the
following output:
$ tc filter show dev swp2 ingress
...
filter protocol ipv6 pref 1000 flower chain 0 handle 0x7c0
eth_type ipv6
dst_ip 2001:db8:1::7bf
skip_sw
in_hw in_hw_count 1
action order 1: police 0x7c0 rate 10Mbit burst 100Kb mtu 2Kb action drop overhead 0b
ref 1 bind 1
not_in_hw
used_hw_stats immediate
The current grep expression matches on both 'in_hw' and 'not_in_hw',
resulting in incorrect results.
Fix that by using JSON output instead.

Change the case that sends packets with "too short inner packet" to
include part of ethernet header, to make the trap to be triggered due to
the correct reason.
According to ASIC arch, the trap is triggered if overlay packet length is
less than 18B, and the minimum inner packet should include source MAC and
destination MAC.
Till now the case passed because one of the reserved bits in VxLAN
header was used. This issue was found while adding an equivalent test
for IPv6.
