Directory: drivers/net/ethernet/xircom
/* [xirc2ps_cs.c wk 03.11.99] (1.40 1999/11/18 00:06:03)
 * Xircom CreditCard Ethernet Adapter IIps driver
 * Xircom Realport 10/100 (RE-100) driver 
 *
 * This driver supports various Xircom CreditCard Ethernet adapters
 * including the CE2, CE IIps, RE-10, CEM28, CEM33, CE33, CEM56,
 * CE3-100, CE3B, RE-100, REM10BT, and REM56G-100.
 *
 * 2000-09-24 <psheer@icon.co.za> The Xircom CE3B-100 may not
 * autodetect the media properly. In this case use the
 * if_port=1 (for 10BaseT) or if_port=4 (for 100BaseT) options
 * to force the media type.
 * 
 * Written originally by Werner Koch based on David Hinds' skeleton of the
 * PCMCIA driver.
