Follow-up Comment #5, bug #28106 (project lwip):
Yes, it looks like in Linux data packet not considered to be dupack.
tcp_send_empty_ack patch
* the whole segment is < rcv_nxt
* if the incoming segment is out-of-sequence
* The incoming segment is not withing the window
* Segments with length 0 out of the window
Yes, first case with old segment could stay with send_ach_now()
I don't know about 4th:
each 0 segment will be answered with 0 segment immediately,
in case erroneous seqno ping-pong will last endless?
