1462 * queues. The upper half is for inbound queues.

1475 * which allows the device driver to track the queue progress without
1476 * PCI reads. When an entry is placed on an inbound queue, the chip will
1477 * update the relevant index register and then copy the value to the
1478 * shadow register in host memory.
