Follow-up Comment #8, task #14128 (project lwip):

Seems like Linux does not bound the CWND increase for a single ACK, this seems
wrong. RFC 5681 "RECOMMEND"s:

cwnd += min(N, SMSS)
where N is the number of previously unacknowledged bytes acknowledged in the
incoming ACK.

I think to accommodate stretch ACK, change SMSS to 2*SMSS here, but I don't
see a reason to leave it unbounded like in Linux.
