Follow-up Comment #5:

Sorry my answer took so long.

I think I now see what the problem is. However, currently I don't really know
a fix to it. Your patch surely breaks at least one of my port's drivers that
implements deferred transmission by keeping the tx pbufs on a list.

I'm not sure whether ip_frag is correct in changing the pbuf, but at least,
TCP probably shouldn't retransmit if p->ref > 1. The tcp retransmit case of
setting the payload pointer back to what it (possibly) was before the first
transmission is kind of odd, I agree. :-)
