[lwip-devel] [bug #2595] loopif results in NULL reference for incoming TCP packets

[Jonathan Larmour]

Follow-up Comment #11, bug #2595 (project lwip):

I think it is possible for someone to use NO_SYS=0 without tcpip_thread. Just
because someone is using the raw API doesn't mean it is a single-threaded
system - it may need to interact with other threads.

However, clearly the user could implement that with their own OS native
functions rather than the lwip sys API. The question is whether we want to
force them to have to do so, even if they might find the sys API convenient.
The answer can be yes, but doesn't have to be. Personally I think yes, and if
so, we need to document it.
