Follow-up Comment #2, bug #21492 (project lwip):

I'm probably being dumb, but can you explain the + 20 in this line:

+    sendmss = LWIP_MIN(sendmss + 20, mss_s);

I would have thought that we should use the MSS received from the remote side
as-is. Otherwise it seems to be adding 20 to the MSS passed in every time.
