-/* SECURE SOCKET IMPLEMENTATION
- *
- *   TRANSMIT:
- *
- *      When the user sends a packet via send() system call
- *      the wanpipe_sendmsg() function is executed.
- *
- *      Each packet is enqueud into sk->sk_write_queue transmit
- *      queue. 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.

- * wanpipe_listen_rcv
- *
- *      Wanpipe LISTEN socket bottom half handler.  This function
- *      is called by the WANPIPE device drivers to queue an
- *      incoming call into the socket listening queue.
- *      Once the packet is queued, the waiting accept() process
- *      is woken up.
- *
- *      During socket bind, this function is bounded into
- *      WANPIPE driver private.
- *
- *      IMPORTANT NOTE:
- *          The accept call() is waiting for an skb packet
- *          which contains a pointer to a device structure.
- *
- *          When we do a bind to a device structre, we
- *          bind a newly created socket into "chan->sk".  Thus,
- *          when accept receives the skb packet, it will know
- *          from which dev it came form, and in turn it will know
- *          the address of the new sock.
- *
- *      NOTE: This function gets called from driver ISR.
