From f350a0a87374418635689471606454abc7beaa3a Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Tue, 15 Jun 2010 06:50:45 +0000 Subject: bridge: use rx_handler_data pointer to store net_bridge_port pointer Register net_bridge_port pointer as rx_handler data pointer. As br_port is removed from struct net_device, another netdev priv_flag is added to indicate the device serves as a bridge port. Also rcuized pointers are now correctly dereferenced in br_fdb.c and in netfilter parts. Signed-off-by: Jiri Pirko Signed-off-by: David S.
