# This is a BitKeeper generated diff -Nru style patch.
#
# ChangeSet
#   2004/12/30 00:28:25-05:00 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.
