| 2 | * Xircom CreditCard Ethernet Adapter IIps driver |
| 3 | * Xircom Realport 10/100 (RE-100) driver |
| 4 | * |
| 5 | * This driver supports various Xircom CreditCard Ethernet adapters |
| 6 | * including the CE2, CE IIps, RE-10, CEM28, CEM33, CE33, CEM56, |
| 7 | * CE3-100, CE3B, RE-100, REM10BT, and REM56G-100. |
| 8 | * |
| 9 | * 2000-09-24 <psheer@icon.co.za> The Xircom CE3B-100 may not |
| 10 | * autodetect the media properly. In this case use the |
| 11 | * if_port=1 (for 10BaseT) or if_port=4 (for 100BaseT) options |
| 12 | * to force the media type. |
