Follow-up Comment #3, bug #27771 (project lwip):
What's happening in Jan's trace is:
- lwIP announces wnd of 512
- lwIP receives 10 bytes of data
- internal rcv_wnd is now 502
- calls recv callback
- recv callback calls tcp_recved
- internal rcv_wnd is now 512
- recv_ann_wnd is still 502
- lwIP sends ACK with an announced wnd of 502
This means the window is decreasing although it wouldn't have to: if the
window size we have was OK to be announced before receiving, it should be OK
to be announced after receiving, shouldn't it?
