selftests: net: tls: check if FIPS mode is enabled
TLS selftests use the ChaCha20-Poly1305 and SM4 algorithms, which are not FIPS compliant. When fips=1, this set of tests fails. Add a check and only run these tests if not in FIPS mode. Fixes: 4f336e88a870 ("selftests/tls: add CHACHA20-POLY1305 to tls selftests") Fixes: e506342a03c7 ("selftests/tls: add SM4 GCM/CCM to tls selftests") Reviewed-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Magali Lemes <magali.lemes@canonical.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
