43f66a6c JK |
5089 | * 0 to 31 |
5090 | * | |
5091 | * Rx Queue Indexes | |
5092 | * The host/firmware share two index registers for managing the Rx buffers. | |
5093 | * | |
bf79451e JG |
5094 | * The READ index maps to the first position that the firmware may be writing |
5095 | * to -- the driver can read up to (but not including) this position and get | |
5096 | * good data. | |
43f66a6c JK |
5097 | * The READ index is managed by the firmware once the card is enabled. |
5098 | * | |
5099 | * The WRITE index maps to the last position the driver has read from -- the | |
5100 | * position preceding WRITE is the last slot the firmware can place a packet. | |
5101 | * | |
5102 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if | |
bf79451e | 5103 | * WRITE = READ. |
43f66a6c | 5104 | * |
bf79451e | 5105 | * During initialization the host sets up the READ queue position to the first |
43f66a6c JK |
5106 | * INDEX position, and WRITE to the last (READ - 1 wrapped) |
5107 | * | |
5108 | * When the firmware places a packet in a buffer it will advance the READ index | |
5109 | * and fire the RX interrupt. The driver can then query the READ index and | |
5110 | * process as many packets as possible, moving the WRITE index forward as it | |
5111 | * resets the Rx queue buffers with new memory. | |
