| 3 | * Ethernet adapters. Based on earlier sk98lin, e100 and |
| 4 | * FreeBSD if_sk drivers. |

| 6 | * This driver intentionally does not support all the features |
| 7 | * of the original driver such as link fail-over and link management because |
| 8 | * those should be done at higher levels. |
