teaming: deliver link-local packets with the link they arrive on
skb is ignored if team port is disabled. We want the skb to be delivered
if it's an link layer packet.
Issue is already fixed for bonding in
commit b89f04c61efe ("bonding: deliver link-local packets with skb->dev set to link that packets arrived on")
changelog:
v2: change LLDP -> link layer in comments/commit descrip, comment format
