Not just "while at it", but I do wonder whether it isn't, in fact, called "deep" for a reason: /* * Lower devices of master uppers (bonding, team) do not have * grp assigned to themselves. Grp is assigned to upper device * instead. */ I haven't tested this, but I wonder if you could actually call __vlan_find_dev_deep_rcu() on the switch port interface and it would cover both this and the bridge having an 8021q upper automatically?
