Attached is a patch to 2.4's ethtool.h to use appropriate, 
userspace-accessible data types (__u8 and friends, rather than u8 and 
friends).

I've also posted a patch against ethtool-1.8 to the sf.net gkernel site 
that cleans-up ethtool-copy.h and the rest in the same manner.

My motivation for the patch is to allow a userspace program to cleanly 
call ethtool ioctls without the typedef'ing used within the ethtool 
package.

Please cc me with responses, as I am not subscribed to lkml.

Thanks,
E
