| 9 | * This device driver works with the following SMC adapters: |
| 10 | * - SMC TokenCard Elite (8115T, chips 825/584) |
| 11 | * - SMC TokenCard Elite/A MCA (8115T/A, chips 825/594) |

| 18 | * |
| 19 | * Changes: |
| 20 | * 07102000 JS Fixed a timing problem in smctr_wait_cmd(); |
| 21 | * Also added a bit more discriptive error msgs. |
| 22 | * 07122000 JS Fixed problem with detecting a card with |
| 23 | * module io/irq/mem specified. |
| 24 | * |
| 25 | * To do: |
| 26 | * 1. Multicast support. |
