Just to play devil's advocate, the latest Intel ethernet drivers are generally 
found at https://sourceforge.net/projects/e1000

These drivers often have fixes/features that haven't made it into the kernel 
yet, and are compilable against a variety of kernel versions rather than just 
the most recent.

Of course the same developers also maintain in-tree kernel drivers, but changes 
to the in-tree drivers only affect the currently-maintained subset of kernel 

Other vendors also maintain out-of-tree drivers as well as in-tree drivers, so 
the situation is exactly analogous to Cinder.
