selftests: forwarding: mirror_gre_vlan_bridge_1q: Add more tests
Offloading of mirror-to-gretap in mlxsw is tricky especially in cases when the gretap underlay involves bridges. Add more tests that exercise the bridge handling code: - forbidden_egress tests that check vlan removal on bridge port in the underlay packet path - untagged_egress tests that similarly check "egress untagged" - fdb_roaming tests that check whether learning FDB on a different port is reflected - stp tests for handling port STP status of bridge egress port Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S.
