Subject: [PATCH net v2] selftests: net: fix rps_default_mask with >32 CPUs

From: Jakub Kicinski <[email-masked]>
Date: Sat, 20 Jan 2024 13:02:56 -0800

If there is more than 32 cpus the bitmask will start to contain
commas, leading to:

./rps_default_mask.sh: line 36: [: 00000000,00000000: integer expression expected

Remove the commas, bash doesn't interpret leading zeroes as oct
so that should be good enough.

Fixes: c12e0d5f267d ("self-tests: introduce self-tests for RPS default mask")
