selftests: mlxsw: qos_mc_aware: Specify arping timeout as an integer

2020-06-07T11:16:48+00:00

[ Upstream commit 46ca11177ed593f39d534f8d2c74ec5344e90c11 ]

Starting from iputils s20190709 (used in Fedora 31), arping does not
support timeout being specified as a decimal:

$ arping -c 1 -I swp1 -b 192.0.2.66 -q -w 0.1
arping: invalid argument: '0.1'

Previously, such timeouts were rounded to an integer.

Fix this by specifying the timeout as an integer.

selftests: mlxsw: Add test cases for local table route replacement

2020-02-07T17:47:01+00:00

Test that routes in the main table do not replace identical routes in
the local table and that routes in the local table do replace identical
routes in the main table.

selftests: mlxsw: Add a TBF selftest

2020-01-25T09:56:31+00:00

Add a test that runs traffic across a port throttled with TBF. The test
checks that the observed throughput is within +-5% from the installed
shaper.

To allow checking both the software datapath and the offloaded one, make
the test suitable for inclusion from driver-specific wrapper. Introduce
such wrappers for mlxsw.

selftests: Move two functions from mlxsw's qos_lib to lib

2020-01-25T09:56:31+00:00

The function humanize() is used for converting value in bits/s to a
human-friendly approximate value in Kbps, Mbps or Gbps. There is nothing
hardware-specific in that, so move the function to lib.sh.

Similarly for the rate() function, which just does a bit of math to
calculate a rate, given two counter values and a time interval.

selftests: mlxsw: qos_mc_aware: Fix mausezahn invocation

2020-01-15T12:16:30+00:00

Mausezahn does not recognize "own" as a keyword on source IP address. As a
result, the MC stream is not running at all, and therefore no UC
degradation can be observed even in principle.

Fix the invocation, and tighten the test: due to the minimum shaper
configured at the MC TCs, we always expect about 20% degradation. Fail the
test if it is lower.
