net: mscc: ocelot: allow offloading of bridge on top of LAG
The blamed commit was too aggressive, and it made ocelot_netdevice_event react only to network interface events emitted for the ocelot switch ports. In fact, only the PRECHANGEUPPER should have had that check. When we ignore all events that are not for us, we miss the fact that the upper of the LAG changes, and the bonding interface gets enslaved to a bridge. This is an operation we could offload under certain conditions.
