    #
    # 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.
