- * 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>

- * <asm/byteorder.h>
- * <asm/io.h>
- * <linux/netdevice.h>
- * <linux/etherdevice.h>
- * <linux/skbuff.h>
- * those three depending on kernel version used:
- * <linux/bios32.h>
- * <linux/init.h>
