Follow-up Comment #1, bug #27504 (project lwip):
The patch looks good to me.
I am a little worried about the tcp_rexmit behaviour. I thought that unacked
+ unsent were supposed to form a continuous, monotonic sequence of segments?
Apparently, so did tcp_enqueue().
Note that tcp_rexmit_rto preserves this invariant as well.
Could tcp_rexmit perhaps call tcp_output_segment directly rather than mucking
about with the queues?
