====================
mlxsw: Adjust QOS tests for Spectrum-4 testing

Amit writes:

Quality Of Service 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. Spectrum-4 ASIC will not
support this speed in all ports, so to be able to run QOS tests there,
some adjustments are required.

Patch set overview:
Patch #1 adjusts qos_ets_strict, qos_mc_aware and sch_ets tests.
Patch #2 adjusts RED tests.
Patch #3 extends devlink_lib to support querying maximum pool size.
Patch #4 adds a test which can be used instead of qos_burst and do not
assume that 1Gbps speed is supported.
Patch #5 removes qos_burst test.

# This test sends 1Gbps of traffic through the switch, into which it then
# injects a burst of traffic and tests that there are no drops.
#
# The 1Gbps stream is created by sending >1Gbps stream from H1. This stream
# ingresses through $swp1, and is forwarded thtrough a small temporary pool to a
# 1Gbps $swp3.
#
# Thus a 1Gbps stream enters $swp4, and is forwarded through a large pool to
# $swp2, and eventually to H2. Since $swp2 is a 1Gbps port as well, no backlog
# is generated.
#
# At this point, a burst of traffic is forwarded from H3. This enters $swp5, is
# forwarded to $swp2, which is fully subscribed by the 1Gbps stream. The
# expectation is that the burst is wholly absorbed by the large pool and no
# drops are caused. After the burst, there should be a backlog that is hard to
# get rid of, because $sw2 is fully subscribed. But because each individual
# packet is scheduled soon after getting enqueued, SLL and HLL do not impact the
# test.

# The failure mode that this specifically tests is exhaustion of descriptor
# buffer. The point is to produce a burst that shared buffer should be able
# to accommodate, but produce it with small enough packets that the machine
# runs out of the descriptor buffer space with default configuration.
#
# The machine therefore needs to be able to produce line rate with as small
# packets as possible, and at the same time have large enough buffer that
# when filled with these small packets, it runs out of descriptors.
# Spectrum-2 is very close, but cannot perform this test. Therefore use
# Spectrum-3 as a minimum, and permit larger burst size, and therefore
# larger packets, to reduce spurious failures.
