When the packet is enqueued, a delayed transmit - * timer is triggerd which acts as a Bottom Half hander. - * - * wanpipe_delay_transmit() function (BH), dequeues packets - * from the sk->sk_write_queue transmit queue and sends it - * to the deriver via dev->hard_start_xmit(skb, dev) function. - * Note, this function is actual a function pointer of if_send() - * routine in the wanpipe driver. - * - * X25API GUARANTEED DELIVERY: - * - * In order to provide 100% guaranteed packet delivery, - * an atomic 'packet_sent' counter is implemented. Counter - * is incremented for each packet enqueued - * into sk->sk_write_queue. Counter is decremented each - * time wanpipe_delayed_transmit() function successfuly - * passes the packet to the driver. Before each send(), a poll - * routine checks the sock resources The maximum value of - * packet sent counter is 1, thus if one packet is queued, the - * application will block until that packet is passed to the - * driver. - * - * RECEIVE: - * - * Wanpipe device drivers call the socket bottom half - * function, wanpipe_rcv() to queue the incoming packets - * into an AF_WANPIPE socket queue. Based on wanpipe_rcv() - * return code, the driver knows whether the packet was - * successfully queued. If the socket queue is full, - * protocol flow control is used by the driver, if any, - * to slow down the traffic until the sock queue is free. - * - * Every time a packet arrives into a socket queue the - * socket wakes up processes which are waiting to receive - * data. - * - * If the socket queue is full, the driver sets a block - * bit which signals the socket to kick the wanpipe driver - * bottom half hander when the socket queue is partialy - * empty. wanpipe_recvmsg() function performs this action. - * - * In case of x25api, packets will never be dropped, since - * flow control is available. - * - * In case of streaming protocols like CHDLC, packets will - * be dropped but the statistics will be generated. - */ - - -/* The code below is used to test memory leaks.
