Hi Stephen:

I'm in the process of writing two new modules fo ip(8), ippolicy and
ipstate which will be a NETLINK based replacement for setkey.

In order to do so, I need to get libnetlink to speak the XFRM protocol.
Thus I've added a new nl_open function which allows the protocol to
be specified.

Cheers,
