#   2005/01/10 00:02:31-05:00 dave@thedillows.org 
#   Add the xfrm offload management calls to struct netdevice.
#   
#   xfrm_state_add() is called for inbound xfrm states
#   xfrm_bundle_add() is called for outbound xfrm bundles
#   xfrm_state_del() is called for all offloaded xfrms,
#   	inbound or outbound.
#   
#   If a driver adds NETIF_F_IPSEC to its features, it must
#   provide all three callbacks.
