2 * Xircom CreditCard Ethernet Adapter IIps driver
3 * Xircom Realport 10/100 (RE-100) driver
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.
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.
