Subject: [PATCH] e1000, e1000e valid-addr fixes

Actually, looking over the code I see obvious bugs in the logic:

An invalid ethernet address should not cause device loading to fail, 
because the user is given the opportunity to supply a MAC address via 
userspace (ifconfig or whatever) before the interface goes up.

I just created the attached -bug fix- patch as illustration, though I 
have not committed it, waiting for comment.

This patch will make no difference for users hitting invalid-eep-csum 
rather than invalid-MAC-addr condition, but it's a problem I noticed 
while reviewing Adam's patch in detail.

	Jeff
