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