| * Xircom CreditCard Ethernet Adapter IIps driver |
| * Xircom Realport 10/100 (RE-100) driver |
| * |
| * This driver supports various Xircom CreditCard Ethernet adapters |
| * including the CE2, CE IIps, RE-10, CEM28, CEM33, CE33, CEM56, |
| * CE3-100, CE3B, RE-100, REM10BT, and REM56G-100. |
| * |
| * 2000-09-24 <psheer@icon.co.za> The Xircom CE3B-100 may not |
| * autodetect the media properly. In this case use the |
| * if_port=1 (for 10BaseT) or if_port=4 (for 100BaseT) options |
| * to force the media type. |
| * |
| * Written originally by Werner Koch based on David Hinds' skeleton of the |
| * PCMCIA driver. |
