[lwip-devel] Duplicate local port number of client in multithreading scenario

[wuchangsheng (C)]

Hi, all:

         In the multithreading scenario, when each thread uses one LwIP, the local port generated by the client may be duplicated. Then I looked at the code and found that in the tcp_new_port function, tcp_port is a global variable. This may result in duplicate ports when multithreading.

    Dose LwIP support multithreading.
