Subject: [PATCH v4 net-next 0/7] Offload software learnt bridge addresses to DSA

From: Vladimir Oltean <vladimir.oltean@nxp.com>

This series tries to make DSA behave a bit more sanely when bridged with
"foreign" (non-DSA) interfaces and source address learning is not
supported on the hardware CPU port (which would make things work more
seamlessly without software intervention). 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.

v3 was posted here:
https://patchwork.kernel.org/project/netdevbpf/cover/20201213140710.1198050-1-vladimir.oltean@nxp.com/

This is a resend of the previous v3 with some added Reviewed-by tags.

Vladimir Oltean (7):
  net: bridge: notify switchdev of disappearance of old FDB entry upon
    migration
  net: dsa: be louder when a non-legacy FDB operation fails
  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
