Subject: [PATCH net-next 15/15] selftests: Add use case section to fcnal-test
From: David Ahern <dsahern@...il.com>
Add use case section to fcnal-test.
Initial test is VRF based with a bridge and vlans. The commands
stem from bug reports fixed by:
a173f066c7cf ("netfilter: bridge: Don't sabotage nf_hook calls from an l3mdev")
cd6428988bf4 ("netfilter: bridge: Don't sabotage nf_hook calls for an l3mdev slave")
