IPsec implementation key_spdacquire

[Rafa Marin Lopez]

Dear all:

I am a newbie in this mailing list and I am not sure whether this is the right place to ask (let me know otherwise)

In the file key.c in netipsec there is a function:

key_spdacquire(struct secpolicy *sp)

which is implemented but in the table:


static int (*key_typesw[])(struct socket *, struct mbuf *,
                  const struct sadb_msghdr *) = {
...

 NULL,           /* SADB_X_SPDACQUIRE */


Does it mean it is not usable? 

We are interested because we are dealing with handling IPsec by using SDN paradigm (https://tools.ietf.org/html/draft-abad-i2nsf-sdn-ipsec-flow-protection-00) and we would need an event when a IP packet needs a policy to be configured for an outbound packet.

Any comments?

Best Regards.
