  * resets the Rx queue buffers with new memory.
  *
  * The management in the driver is as follows:
- * + A list of pre-allocated RBDs is stored in iwl->rxq->rx_free.
- *   When the interrupt handler is called, the request is processed.
- *   The page is either stolen - transferred to the upper layer
- *   or reused - added immediately to the iwl->rxq->rx_free list.
- * + When the page is stolen - the driver updates the matching queue's used
- *   count, detaches the RBD and transfers it to the queue used list.
- *   When there are two used RBDs - they are transferred to the allocator empty
- *   list. Work is then scheduled for the allocator to start allocating
- *   eight buffers.
- *   When there are another 6 used RBDs - they are transferred to the allocator
- *   empty list and the driver tries to claim the pre-allocated buffers and
- *   add them to iwl->rxq->rx_free. If it fails - it continues to claim them
- *   until ready.
- *   When there are 8+ buffers in the free list - either from allocation or from
- *   8 reused unstolen pages - restock is called to update the FW and indexes.
- * + In order to make sure the allocator always has RBDs to use for allocation
- *   the allocator has initial pool in the size of num_queues*(8-2) - the
- *   maximum missing RBDs per allocation request (request posted with 2
- *    empty RBDs, there is no guarantee when the other 6 RBDs are supplied).
- *   The queues supplies the recycle of the rest of the RBDs.
+ * + A list of pre-allocated SKBs is stored in iwl->rxq->rx_free.  When
+ *   iwl->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled
+ *   to replenish the iwl->rxq->rx_free.
+ * + In iwl_pcie_rx_replenish (scheduled) if 'processed' != 'read' then the
+ *   iwl->rxq is replenished and the READ INDEX is updated (updating the
+ *   'processed' and 'read' driver indexes as well)
  * + A received packet is processed and handed to the kernel network stack,
  *   detached from the iwl->rxq.  The driver 'processed' index is updated.
- * + If there are no allocated buffers in iwl->rxq->rx_free,
+ * + The Host/Firmware iwl->rxq is replenished at irq thread time from the
+ *   rx_free list. If there are no allocated buffers in iwl->rxq->rx_free,
  *   the READ INDEX is not incremented and iwl->status(RX_STALLED) is set.
