   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.
