[lwip-users] bug #2240 - UDP pcb connect behaviour

[Leon Woestenberg]

Ed Suller submitted this bug report. (Thanks Ed.)

This behaviour corresponds with accept() or connect(), where the socket
connects with the
remote IP address and remote UDP port address. Ed's fix probably implements
recvfrom() behaviour,
where the socket stays unconnected to a remote address.

None of both is wrong, but we should make both available and especially well
documented.
