[PATCH v2 net-next 4/4] selftests: forwarding: add test of MAC-Auth Bypass to locked port tests

Hans Schultz
2022-03-17T09:39:53Z

Verify that the MAC-Auth mechanism works by adding a FDB entry with the
locked flag set. denying access until the FDB entry is replaced with a
FDB entry without the locked flag set.
