Assuming that you are porting lwIP on some multi-threaded system...

netconn_new_with_proto_and_callback() sends a msg to conn->mbox
and waits for tcpip_thread processing it.

tcpip_thread will handle the msg and call
sys_mbox_post(msg->conn->mbox, NULL) at the end of do_new_conn() in
api_msg.c.

Hope that helps,
