10 | * Acorn ether1 driver (82586 chip) for Acorn machines | |
11 | * | |
12 | * We basically keep two queues in the cards memory - one for transmit | |
13 | * and one for receive. Each has a head and a tail. The head is where | |
14 | * we/the chip adds packets to be transmitted/received, and the tail | |
15 | * is where the transmitter has got to/where the receiver will stop. | |
16 | * Both of these queues are circular, and since the chip is running | |
17 | * all the time, we have to be careful when we modify the pointers etc | |
18 | * so that the buffer memory contents is valid all the time. | |
19 | * | |
20 | * Change log: | |
21 | * 1.00 RMK Released | |
22 | * 1.01 RMK 19/03/1996 Transfers the last odd byte onto/off of the card now. | |
23 | * 1.02 RMK 25/05/1997 Added code to restart RU if it goes not ready | |
24 | * 1.03 RMK 14/09/1997 Cleaned up the handling of a reset during the TX interrupt. | |
25 | * Should prevent lockup. | |
26 | * 1.04 RMK 17/09/1997 Added more info when initialsation of chip goes wrong. | |
27 | * TDR now only reports failure when chip reports non-zero | |
28 | * TDR time-distance. | |
29 | * 1.05 RMK 31/12/1997 Removed calls to dev_tint for 2.1 | |
30 | * 1.06 RMK 10/02/2000 Updated for 2.3.43 | |
31 | * 1.07 RMK 13/05/2000 Updated for 2.3.99-pre8 | |
