Merge branch 'FDB-updates-for-SJA1105-DSA-driver'

Vladimir Oltean says:

====================
FDB updates for SJA1105 DSA driver

This patch series adds:

- FDB switchdev support for the second generation of switches (P/Q/R/S).
  I could test/code these now that I got a board with a SJA1105Q.

- Management route support for SJA1105 P/Q/R/S. This is needed to send
  PTP/STP/management frames over the CPU port.

- Logic to hide private DSA VLANs from the 'bridge fdb' commands.

The new FDB code was also tested and still works on SJA1105T.
