selftests: net: bridge: add vlan mcast snooping control test
Add the first test for bridge per-vlan multicast snooping which checks if control of the global and per-vlan options work as expected, joins and leaves are tested at each option value. TEST: Vlan multicast snooping enable [ OK ] TEST: Vlan global options existence [ OK ] TEST: Vlan mcast_snooping global option default value [ OK ] TEST: Vlan 10 multicast snooping control [ OK ] Signed-off-by: Nikolay Aleksandrov <nikolay@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
