/* [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 <[email protected]> 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. |
