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

[Kieran Mansley]

Follow-up Comment #4, bug #26012 (project lwip):

Thanks for taking a look.

I don't see why the other side would need to retransmit anything.  Can you
explain?

The data should be ACKed already by tcp_receive().  All that the tcp_recved()
function is doing is working out whether a window update is necessary.  Window
updates shouldn't affect retransmissions at all.
