Commit Message

Magali Lemes June 9, 2023, 4:43 p.m. UTC 
There are some MD5 tests which fail when the kernel is in FIPS mode,
since MD5 is not FIPS compliant. Add a check and only run those tests
if FIPS mode is not enabled.

Fixes: f0bee1ebb5594 ("fcnal-test: Add TCP MD5 tests")
Fixes: 5cad8bce26e01 ("fcnal-test: Add TCP MD5 tests for VRF")
Reviewed-by: David Ahern <dsahern@kernel.org>

Changes in v2:
 - Add R-b tag.
