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 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
...

eth_type ipv6
dst_ip 2001:db8:1::7bf

action order 1: police 0x7c0 rate 10Mbit burst 100Kb mtu 2Kb action drop overhead 0b
ref 1 bind 1
not_in_hw

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

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.

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.

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.
