[Bridge] Bridge and PACKET-socket
Ahoy,
I've encountered some confusing semantics with using PACKET(7) sockets
on bridge-enslaved interfaces. Specifically, if my socket accepts all
types of frame (bind() to ETH_P_ALL) then it gets all packets; but if

packets at all.
That is how it's coded in net/core/dev.c's netif_receive_skb(). First
