2496 * The IPW device contains a Microwire compatible EEPROM that stores
2497 * various data like the MAC address. Usually the firmware has exclusive
2498 * access to the eeprom, but during device initialization (before the
2499 * device driver has sent the HostComplete command to the firmware) the
2500 * device driver has read access to the EEPROM by way of indirect addressing
2501 * through a couple of memory mapped registers.
2502 *
2503 * The following is a simplified implementation for pulling data out of the
2504 * the eeprom, along with some helper functions to find information in
2505 * the per device private data's copy of the eeprom.
2506 *
2507 * NOTE: To better understand how these functions work (i.e what is a chip
2508 * select and why do have to keep driving the eeprom clock?), read
2509 * just about any data sheet for a Microwire compatible EEPROM.

4949 *
4950 * The WRITE index maps to the last position the driver has read from -- the

bf79451e 4956 * During initialization the host sets up the READ queue position to the first
43f66a6c

4958 *
4959 * When the firmware places a packet in a buffer it will advance the READ index

4973 * + The Host/Firmware ipw->rxq is replenished at tasklet time from the rx_free
