  1 /* [xirc2ps_cs.c wk 03.11.99] (1.40 1999/11/18 00:06:03)
  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.
