  93  * Since we can't queue our bulk write urbs (don't know why - it just
  94  * doesn't work), we can send down only one write urb at a time. The simplistic
  95  * approach taken by the generic usbserial driver will work, but it's not good
  96  * for performance. Therefore, we buffer upto URBDATA_QUEUE_MAX bytes of write
  97  * requests coming from the line discipline. This is done by chaining them
  98  * in lists of struct ipaq_packet, each packet holding a maximum of
  99  * PACKET_SIZE bytes.
 100  *
 101  * ipaq_write() can be called from bottom half context; hence we can't
 102  * allocate memory for packets there. So we initialize a pool of packets at
 103  * the first open and maintain a freelist.
 104  *
 105  * The value of PACKET_SIZE was empirically determined by
 106  * checking the maximum write sizes sent down by the ppp ldisc.
 107  * URBDATA_QUEUE_MAX is set to 64K, which is the maximum TCP window size.
