35 | * A driver for Xircom ethernet PC-cards. |
36 | * |
37 | * The driver has been inspired by the xirc2ps_cs.c driver found in Linux' |
38 | * PCMCIA package written by Werner Koch <werner.koch@guug.de>: |
39 | * [xirc2ps_cs.c wk 14.04.97] (1.31 1998/12/09 19:32:55) |
40 | * I will note that no code was used verbatim from that driver as it is under |
41 | * the much too strong GNU General Public License, it was only used as a |
42 | * "specification" of sorts. |
43 | * Other inspirations have been if_fxp.c, if_ep_pcmcia.c and elink3.c as |
44 | * they were found in OpenBSD 2.4. |
