Subject: [PATCH net-next 0/2] Plug the last 2 holes in the switchdev notifiers for local FDB entries

The work for trapping local FDB entries to the CPU in switchdev/DSA
started with the "RX filtering in DSA" series:
https://patchwork.kernel.org/project/netdevbpf/cover/20210629140658.2510288-1-olteanv@gmail.com/
and was continued with further improvements such as "Fan out FDB entries
pointing towards the bridge to all switchdev member ports":
https://patchwork.kernel.org/project/netdevbpf/cover/20210719135140.278938-1-vladimir.oltean@nxp.com/
https://patchwork.kernel.org/project/netdevbpf/cover/20210720173557.999534-1-vladimir.oltean@nxp.com/

There are only 2 more issues left to be addressed (famous last words),
and these are:
- dynamically learned FDB entries towards interfaces foreign to DSA need
  to be replayed too
- adding/deleting a VLAN on a port causes the local FDB entries in that
  VLAN to be prematurely deleted

This patch series addresses both, and patch 2 depends on 1 to work properly.

Vladimir Oltean (2):
  net: bridge: switchdev: replay the entire FDB for each port
  net: bridge: switchdev: treat local FDBs the same as entries towards
    the bridge
