| 3858 | * |
| 3859 | * The host allocates 32 DMA target addresses and passes the host address |
| 3860 | * to the firmware at register CX2_RFDS_TABLE_LOWER + N * RFD_SIZE where N is |
| 3861 | * 0 to 31 |
| 3862 | * |
| 3863 | * Rx Queue Indexes |
| 3864 | * The host/firmware share two index registers for managing the Rx buffers. |
| 3865 | * |
Jeff Garzik | bf79451 | 2005-07-31 13:07:26 -0400 | [diff] [blame] | 3866 | * The READ index maps to the first position that the firmware may be writing |
| 3867 | * to -- the driver can read up to (but not including) this position and get |
| 3868 | * good data. |
James Ketrenos | 43f66a6 | 2005-03-25 12:31:53 -0600 | [diff] [blame] | 3869 | * The READ index is managed by the firmware once the card is enabled. |
| 3870 | * |
| 3871 | * The WRITE index maps to the last position the driver has read from -- the |
| 3872 | * position preceding WRITE is the last slot the firmware can place a packet. |
| 3873 | * |
| 3874 | * The queue is empty (no good data) if WRITE = READ - 1, and is full if |

| 3879 | * |
| 3880 | * When the firmware places a packet in a buffer it will advance the READ index |
| 3881 | * and fire the RX interrupt. The driver can then query the READ index and |
| 3882 | * process as many packets as possible, moving the WRITE index forward as it |
| 3883 | * resets the Rx queue buffers with new memory. |
