4 | * Jean II - HPLB '96 | |
5 | * | |
6 | * Reorganisation and extension of the driver. | |
7 | * Original copyright follow. See wavelan_cs.p.h for details. | |
8 | * | |
9 | * This code is derived from Anthony D. Joseph's code and all the changes here | |
10 | * are also under the original copyright below. | |
11 | * | |
12 | * This code supports version 2.00 of WaveLAN/PCMCIA cards (2.4GHz), and | |
13 | * can work on Linux 2.0.36 with support of David Hinds' PCMCIA Card Services | |
14 | * | |
15 | * Joe Finney (joe@comp.lancs.ac.uk) at Lancaster University in UK added | |
16 | * critical code in the routine to initialize the Modem Management Controller. | |
17 | * | |
18 | * Thanks to Alan Cox and Bruce Janson for their advice. | |

35 | * Joseph O'Sullivan & John Langford (josullvn@cs.cmu.edu & jcl@cs.cmu.edu) | |
36 | * | |
37 | * Apr 2 '98 made changes to bring the i82593 control/int handling in line | |
38 | * with offical specs... | |
