[RFC,net-next,0/3] Offload learnt bridge addresses to DSA

Message

This small series tries to make DSA behave a bit more sanely when
bridged with "foreign" (non-DSA) interfaces. When a station A connected
to a DSA switch port needs to talk to another station B connected to a
non-DSA port through the Linux bridge, DSA must explicitly add a route
for station B towards its CPU port. It cannot rely on hardware address
learning for that.

Vladimir Oltean (3):
  net: dsa: don't use switchdev_notifier_fdb_info in
    dsa_switchdev_event_work
  net: dsa: move switchdev event implementation under the same
    switch/case statement
  net: dsa: listen for SWITCHDEV_{FDB,DEL}_ADD_TO_DEVICE on foreign
    bridge neighbors
