Subject: [PATCH v2 net-next 0/6] Offload software learnt bridge addresses to DSA

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.

Initial RFC was posted here:
https://www.spinics.net/lists/netdev/msg698169.html

Vladimir Oltean (6):
  net: bridge: notify switchdev of disappearance of old FDB entry upon
    migration
  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: exit early in dsa_slave_switchdev_event if we can't program
    the FDB
  net: dsa: listen for SWITCHDEV_{FDB,DEL}_ADD_TO_DEVICE on foreign
    bridge neighbors
  net: dsa: ocelot: request DSA to fix up lack of address learning on
    CPU port
