      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.
