Subject: [PATCH net-next mlxsw v2 16/16] selftests: forwarding: bridge_mdb_max: Add a new selftest
Add a suite covering mcast_n_groups and mcast_max_groups bridge features.
Signed-off-by: Petr Machata <petrm@...dia.com>
---
Notes:
v2:
- Adjust the tests that check setting max below n and
reset of max on VLAN snooping enablement
- Make test naming uniform
- Enable testing of control path (IGMP/MLD) in
mcast_vlan_snooping bridge
- Reorganize the code so that test instances (per bridge
type and configuration type) always come right after
the test, in order of {d,q,qvs}{4,6}{cfg,ctl}.
Then groups of selftests are at the end of the file.
Similarly adjust invocation order of the tests.
