0002  * Xircom CreditCard Ethernet Adapter IIps driver
0003  * Xircom Realport 10/100 (RE-100) driver
0004  *
0005  * This driver supports various Xircom CreditCard Ethernet adapters
0006  * including the CE2, CE IIps, RE-10, CEM28, CEM33, CE33, CEM56,
0007  * CE3-100, CE3B, RE-100, REM10BT, and REM56G-100.
0008  *
0009  * 2000-09-24 <psheer@icon.co.za> The Xircom CE3B-100 may not
0010  * autodetect the media properly. In this case use the
0011  * if_port=1 (for 10BaseT) or if_port=4 (for 100BaseT) options
0012  * to force the media type.
0013  *
0014  * Written originally by Werner Koch based on David Hinds' skeleton of the
0015  * PCMCIA driver.
