[Bridge] [PATCH net-next 00/10] selftests: net: bridge: vlan multicast tests

From: Nikolay Aleksandrov <nikolay at nvidia.com>

Hi,
This patch-set adds selftests for the new vlan multicast options that
were recently added. Most of the tests check for default values,
changing options and try to verify that the changes actually take
effect. The last test checks if the dependency between vlan_filtering
and mcast_vlan_snooping holds. The rest are pretty self-explanatory.

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 ]

[Bridge] [PATCH net-next 01/10] selftests: net: bridge: add vlan mcast snooping control test

From: Nikolay Aleksandrov <nikolay at nvidia.com>

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 ]

[Bridge] [PATCH net-next 02/10] selftests: net: bridge: add vlan mcast querier test

From: Nikolay Aleksandrov <nikolay at nvidia.com>

Add a test to try the new global vlan mcast_querier control and also
verify that tagged general query packets are properly generated when
querier is enabled for a single vlan.

TEST: Vlan mcast_querier global option default value                [ OK ]
TEST: Vlan 10 multicast querier enable                              [ OK ]
TEST: Vlan 10 tagged IGMPv2 general query sent                      [ OK ]
TEST: Vlan 10 tagged MLD general query sent                         [ OK ]

[Bridge] [PATCH net-next 05/10] selftests: net: bridge: add vlan mcast_startup_query_count/interval tests

From: Nikolay Aleksandrov <nikolay at nvidia.com>

Add tests which change the new per-vlan startup query count/interval
options and verify the proper number of queries are sent in the expected
interval.

TEST: Vlan mcast_startup_query_interval global option default value   [ OK ]
TEST: Vlan mcast_startup_query_count global option default value    [ OK ]
TEST: Vlan 10 mcast_startup_query_interval option changed to 100    [ OK ]
TEST: Vlan 10 mcast_startup_query_count option changed to 3         [ OK ]

[Bridge] [PATCH net-next 10/10] selftests: net: bridge: add test for vlan_filtering dependency

From: Nikolay Aleksandrov <nikolay at nvidia.com>

Add a test for dependency of mcast_vlan_snooping on vlan_filtering. If
vlan_filtering gets disabled, then mcast_vlan_snooping must be
automatically disabled as well.

TEST: Disable multicast vlan snooping when vlan filtering is disabled   [ OK ]
