[lwip-devel] [patch #5960] Enable multithread send/recv operations on same socket on TCP netconns

[Simon Goldschmidt]

Follow-up Comment #16, patch #5960 (project lwip):

>In a first step, I propose to replace the conn->mbox by a conn->apisem. Good
for you?

Yes. If we integrate the semaphore to use in one of the messages, we can make
tcpip.c and api_msg.c independent of the type of semaphore (per-conn vs.
per-thread) and can use one or the other depending on a configuration switch.
That way systems not having per-thread storage can use the old mechanism to be
faster while lacking "multithread send/recv operations on same socket on TCP
netconns". (I would make the per-thread the default to keep users from being
confused!)
