--------------------------------

[ Upstream commit d7a2fc14 ]

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: f0bee1eb ("fcnal-test: Add TCP MD5 tests")
Fixes: 5cad8bce ("fcnal-test: Add TCP MD5 tests for VRF")
