These get + * used not only for Rx frames, but for any command response or notification + * from the NIC. The driver and NIC manage the Rx buffers by means + * of indexes into the circular buffer. + * + * Rx Queue Indexes + * The host/firmware share two index registers for managing the Rx buffers. + * + * The READ index maps to the first position that the firmware may be writing + * to -- the driver can read up to (but not including) this position and get + * good data. + * The READ index is managed by the firmware once the card is enabled. + * + * The WRITE index maps to the last position the driver has read from -- the + * position preceding WRITE is the last slot the firmware can place a packet. + * + * The queue is empty (no good data) if WRITE = READ - 1, and is full if + * WRITE = READ. + * + * During initialization, the host sets up the READ queue position to the first + * INDEX position, and WRITE to the last (READ - 1 wrapped) + * + * When the firmware places a packet in a buffer, it will advance the READ index + * and fire the RX interrupt. The driver can then query the READ index and + * process as many packets as possible, moving the WRITE index forward as it + * resets the Rx queue buffers with new memory. + * + * The management in the driver is as follows: + * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.

The driver 'processed' index is updated. + * + The Host/Firmware iwl->rxq is replenished at tasklet time from the rx_free + * list.
