[v2,net-next,0/8] net: dsa: mv88e6xxx: Offload bridge port flags

Message

Add support for offloading learning and broadcast flooding flags. With
this in place, mv88e6xx supports offloading of all bridge port flags
that are currently supported by the bridge.

Broadcast flooding is somewhat awkward to control as there is no
per-port bit for this like there is for unknown unicast and unknown
multicast. Instead we have to update the ATU entry for the broadcast
address for all currently used FIDs.

v1 -> v2:
  - Ensure that mv88e6xxx_vtu_get handles VID 0 (Vladimir)
  - Fixed off-by-one in mv88e6xxx_port_set_assoc_vector (Vladimir)
  - Fast age all entries on port when disabling learning (Vladimir)
  - Correctly detect bridge flags on LAG ports (Vladimir)
