The answer would seem to be that when tcp_rexmit is called from the fast
retransmit code, it moves *all* unacked segments to the unsent queue,
which will mean *all* unacked segments are retransmitted. This is not
what should happen. Does anyone know why this change was made? There
could be a good reason for it that I've not thought of.
Thanks
