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. |
13 | * |
14 | * Written originally by Werner Koch based on David Hinds' skeleton of the |
15 | * PCMCIA driver. |
