 * Description:
 *
 *	This is the main module of the Linux GE driver.
 *	
 *	All source files except skge.c, skdrv1st.h, skdrv2nd.h and sktypes.h
 *	are part of SysKonnect's COMMON MODULES for the SK-98xx adapters.
 *	Those are used for drivers on multiple OS', so some thing may seem
 *	unnecessary complicated on Linux. Please do not try to 'clean up'
 *	them without VERY good reasons, because this will make it more
 *	difficult to keep the Linux driver in synchronisation with the
 *	other versions.
 *
 * Include file hierarchy:
 *
 *	<linux/module.h>
 *
 *	"h/skdrv1st.h"
 *		<linux/types.h>
 *		<linux/kernel.h>
 *		<linux/string.h>
