My question about MSS wasn't clear– what I mean is, to an application (like
tcpecho or tcpblaster), the size of MSS shouldn't matter. Shouldn't the
application be able to send as many bytes as it wants? The TCP stack
divides the stream up into chunks (of MSS length) and transmits them...
sending more than MSS bytes should not hang the application...?
Yes, that is correct.
That's not what I"m seeing with the NuttX that I'm using (SAMA5D36-Xplained
using the gigabit ethernet port, built from the latest master).
Do you have write buffering enabled? Do you have enough IOBs
pre-allocated? Have you tried looking at the traffic with WireShark?
