Subject: [PATCH net-next 14/14] selftests: forwarding: Add bridge MDB test
Add a selftests that includes the following test cases:
1. Configuration tests. Both valid and invalid configurations are
tested across all entry types (e.g., L2, IPv4).
2. Forwarding tests. Both host and port group entries are tested across
all entry types.
3. Interaction between user installed MDB entries and IGMP / MLD control
packets.
Example output:
INFO: # Host entries configuration tests
TEST: Common host entries configuration tests (IPv4) [ OK ]
TEST: Common host entries configuration tests (IPv6) [ OK ]
TEST: Common host entries configuration tests (L2) [ OK ]
INFO: # Port group entries configuration tests - (*, G)
