3689 | * For Tx queue, there are low mark and high mark limits. If, after queuing | |

3694 | * The IPW operates with six queues, one receive queue in the device's | |

43f66a6c | 3697 | * |
bf79451e | 3698 | * The four transmit queues allow for performing quality of service (qos) |
43f66a6c | 3699 | * transmissions as per the 802.11 protocol. Currently Linux does not |

43f66a6c JK |
5117 | * INDEX position, and WRITE to the last (READ - 1 wrapped) |
5118 | * | |
5119 | * When the firmware places a packet in a buffer it will advance the READ index | |
5120 | * and fire the RX interrupt. The driver can then query the READ index and | |
5121 | * process as many packets as possible, moving the WRITE index forward as it | |
5122 | * resets the Rx queue buffers with new memory. | |
bf79451e | 5123 | * |
43f66a6c | 5124 | * The management in the driver is as follows: |
bf79451e | 5125 | * + A list of pre-allocated SKBs is stored in ipw->rxq->rx_free. When |
43f66a6c | 5126 | * ipw->rxq->free_count drops to or below RX_LOW_WATERMARK, work is scheduled |
bf79451e | 5127 | * to replensish the ipw->rxq->rx_free. |
43f66a6c JK |
5128 | * + In ipw_rx_queue_replenish (scheduled) if 'processed' != 'read' then the |
5129 | * ipw->rxq is replenished and the READ INDEX is updated (updating the | |
5130 | * 'processed' and 'read' driver indexes as well) | |
5131 | * + A received packet is processed and handed to the kernel network stack, | |
5132 | * detached from the ipw->rxq. The driver 'processed' index is updated. | |
5133 | * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free | |
bf79451e JG |
5134 | * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ |
5135 | * INDEX is not incremented and ipw->status(RX_STALLED) is set. If there | |
43f66a6c JK |
5136 | * were enough free buffers and RX_STALLED is set it is cleared. |
