selftests: mlxsw: Update ping limits (f3b05bb8) · Commits · 戴 / test

The current ping intervals are too short for running mirroring tests in simulator. This leads to ping sending a follow-up ping before the reply arrives, thus sending more than the requested 10 ICMP requests. This traffic is seen at the counters, and causes spurious failures. Bump interval and timeout numbers 5x in mirroring tests to address the spurious failures. Signed-off-by:
