net: ocelot: fix switchdev objects synced for wrong netdev with LAG offload
The point with a *dev and a *brport_dev is that when we have a LAG net device that is a bridge port, *dev is an ocelot net device and *brport_dev is the bonding/team net device. The ocelot net device beneath the LAG does not exist from the bridge's perspective, so we need to sync the switchdev objects belonging to the brport_dev and not to the dev. Fixes: e4bd44e89dcf ("net: ocelot: replay switchdev events when joining bridge") Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
