[Bridge] [PATCH] (6/6) bridge: receive path optimization

[shemminger at osdl.org (Stephen Hemminger)]

This improves the bridge local receive path by avoiding going
through another softirq.  The bridge receive path is already being called 
from a netif_receive_skb() there is no point in going through another
receiveq round trip. 

Recursion is limited because bridge can never be a port of a bridge
so handle_bridge() always returns.
