The recv callback in tcp_pcb (that is called if LWIP_CALLBACK_API=1) has an argument err. Now it seems that this callback is only called (through the define TCP_EVENT_RECV) from tcp_input(). And from there, always with err = ERR_OK!
What is this argument for then, if it's always ERR_OK??? Couldn't we remove it? Does anyone know more about that?
