Subject: [PATCH net-next 3/9] selftests: forwarding: Test action VLAN modify
From: Danielle Ratson <danieller@...lanox.com>
Construct a basic topology consisting of two hosts connected using a
VLAN-aware bridge. Put each port in a different VLAN and test that ping
fails.
Add ingress and egress filters with a VLAN modify action and test that
ping passes.
