    bridge/fdb: add flag/indication for FDB entry synced from offload device

    Add NTF_EXT_LEARNED flag to neigh flags to indicate FDB entry learned by
    device has been learned externally to bridge FDB.  For these entries,
    add "external" annotation in bridge fdb show output:

      00:02:00:00:03:00 dev swp2 used 2/2 master br0 external
      00:02:00:00:03:00 dev swp2 self permanent

    In the example above, 00:02:00:00:03:00 is shown twice on dev swp2.  The
    first entry if from the bridge (master) and is marked as "external" by
    the offload device.  The second entry is from the brport offload device (self),
    and was learned by the device.
