[lwip-users] Are recv/send/write reentrant if LWIP_NETCONN_FULLDUPLEX enabled?

[Grant Edwards]

My (newly generated 2.1.3) documentation says that
LWIP_NETCONN_FULLDUPLEX "allows reading from one thread, writing from
a 2nd thread and closing from a 3rd thread". [And the "really alpha"
statement is indeed gone.]

I assume that does not imply that recv/send/write are renntrant such
that two threads could write to a socket/netconn at the same time? Two
sockets reading at the same time is less common, but would be another
example.

This situation doesn't really make much sense for TCP, but I have seen
applications where it is done for UDP and raw Ethernet.
