23 |
|
|

|
24 |
|
|

|

|
**

** Being given that this driver originates from the FreeBSD version, and
|
28 |
|
|
** in order to keep synergy on both, any suggested enhancements and corrections
|
29 |
|
|
** received on Linux are automatically a potential candidate for the FreeBSD
|
30 |
|
|
** version.
|
31 |
|
|
**
|
32 |
|
|
** The original driver has been written for 386bsd and FreeBSD by

33 |

** Wolfgang Stanglmeier <wolf@cologne.de>

|
|
** Stefan Esser <se@mi.Uni-Koeln.de>
