Hi

Thanks for the answer, we were testing BIRD on FreeBSD 10, so we did not
notice this API change.

I am bit confused by [1] w.r.t. whether ip_len is expected to contain
whole packet length or just data length. In BIRD, we always set it to
whole packet length and it worked, but according to [1] it should be
whole packet length on FreeBSD 10+ and just data length on older ones.

But as we use it only for TX, it is possible that BIRD just sends OSPF
packets that contain additional 20B garbage at the end. OSPF would
tolerate that.
