selftests: forwarding: Add layer 2 miss test cases
Add test cases to verify that the bridge driver correctly marks layer 2 misses only when it should and that the flower classifier can match on this metadata. Example output: # ./tc_flower_l2_miss.sh TEST: L2 miss - Unicast [ OK ] TEST: L2 miss - Multicast (IPv4) [ OK ] TEST: L2 miss - Multicast (IPv6) [ OK ] TEST: L2 miss - Link-local multicast (IPv4) [ OK ] TEST: L2 miss - Link-local multicast (IPv6) [ OK ] TEST: L2 miss - Broadcast [ OK ] Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
