Subject: [PATCH net 0/6] FDB fixes for NXP SJA1105

I have some upcoming patches that make heavy use of statically installed
FDB entries, and when testing them on SJA1105P/Q/R/S and SJA1110, it
became clear that these switches do not behave reliably at all.

- On SJA1110, a static FDB entry cannot be installed at all
- On SJA1105P/Q/R/S, it is very picky about the inner/outer VLAN type
- Dynamically learned entries will make us not install static ones, or
  even if we do, they might not take effect

Patch 5/6 has a conflict with net-next (sorry), the commit message of
that patch describes how to deal with it. Thanks.

Vladimir Oltean (6):
  net: dsa: sja1105: fix static FDB writes for SJA1110
  net: dsa: sja1105: overwrite dynamic FDB entries with static ones in
    .port_fdb_add
  net: dsa: sja1105: invalidate dynamic FDB entries learned concurrently
    with statically added ones
  net: dsa: sja1105: ignore the FDB entry for unknown multicast when
    adding a new address
  net: dsa: sja1105: be stateless with FDB entries on
    SJA1105P/Q/R/S/SJA1110 too
  net: dsa: sja1105: match FDB entries regardless of inner/outer VLAN
