The patch is complete, sorry for being unclear.

xfrm_send_mapping is an implementation of a xfrm_mgr operation.

This operation is invoked from net/ipv4/esp4.c through the
km_new_mapping() function, km_new_mapping() invokes all registered key
managers. It is already implemented in the PF_KEY interface (pfkeyv2_mgr
in af_key.c), but is missing in the netlink xfrm interface. The patch
adds this functionality to the netlink interface.
