[lwip-devel] [bug #26012] ACKs by SWS avoidance

Follow-up Comment #3, bug #26012 (project lwip):

I have seen this patch.
It looks good for me.

It would be nice to add time stamp to pcb
(something like rcv_ann_right_edge_time).
Than it would be possible to send explicit window update from tcp_recved()
for case with slow application data read.

if ( old_rcv_ann_wnd < mss &&
     pcb->rcv_ann_wnd > mss &&
     time_now > (pcb->rcv_ann_right_edge_time + 0.5 sec) ) {
  tcp_ack_now(pcb);
}

Without it other side have to retransmit due to retransmission timeout.
