bf79451e 5018 * During initialization the host sets up the READ queue position to the first
43f66a6c
JK		 5019 * INDEX position, and WRITE to the last (READ - 1 wrapped)
5020 *
5021 * When the firmware places a packet in a buffer it will advance the READ index
5022 * and fire the RX interrupt. The driver can then query the READ index and
5023 * process as many packets as possible, moving the WRITE index forward as it
5024 * resets the Rx queue buffers with new memory.
bf79451e 5025 *
43f66a6c 5026 * The management in the driver is as follows:

5033 * + A received packet is processed and handed to the kernel network stack,
5034 * detached from the ipw->rxq. The driver 'processed' index is updated.
5035 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 5036 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
5037 * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there
