Subject: selftests: mlxsw: Reduce test run time
X-Git-Tag: v6.1-rc5~2768^2~98^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e860419684b547dd4daa8143ad70a97955571482;p=platform%2Fkernel%2Flinux-starfive.git

selftests: mlxsw: Reduce test run time

Instead of iterating over all the available trap policers, only perform
the tests with three policers: The first, the last and the one in the
middle of the range. On a Spectrum-3 system, this reduces the run time
from almost an hour to a few minutes.
