2485 * The IPW device contains a Microwire compatible EEPROM that stores
2486 * various data like the MAC address. Usually the firmware has exclusive
2487 * access to the eeprom, but during device initialization (before the
2488 * device driver has sent the HostComplete command to the firmware) the
2489 * device driver has read access to the EEPROM by way of indirect addressing
2490 * through a couple of memory mapped registers.
2491 *
2492 * The following is a simplified implementation for pulling data out of the
2493 * the eeprom, along with some helper functions to find information in
2494 * the per device private data's copy of the eeprom.
2495 *
2496 * NOTE: To better understand how these functions work (i.e what is a chip
2497 * select and why do have to keep driving the eeprom clock?), read
2498 * just about any data sheet for a Microwire compatible EEPROM.

43f66a6c
JK		 4932 * The READ index is managed by the firmware once the card is enabled.
4933 *
4934 * The WRITE index maps to the last position the driver has read from -- the

4936 *
4937 * The queue is empty (no good data) if WRITE = READ - 1, and is full if
bf79451e 4938 * WRITE = READ.
43f66a6c 4939 *
bf79451e 4940 * During initialization the host sets up the READ queue position to the first
43f66a6c
JK		 4941 * INDEX position, and WRITE to the last (READ - 1 wrapped)
4942 *
4943 * When the firmware places a packet in a buffer it will advance the READ index
4944 * and fire the RX interrupt. The driver can then query the READ index and
4945 * process as many packets as possible, moving the WRITE index forward as it
4946 * resets the Rx queue buffers with new memory.

4955 * + A received packet is processed and handed to the kernel network stack,

4957 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
bf79451e
JG		 4958 * list. If there are no allocated buffers in ipw->rxq->rx_free, the READ
