Any reason to not use netdev_priv() ?

I would not mind an empty line between the declaration of variables
and the actual code.

I'm keeping the style of the rest of the driver, when more pressing 
issues (wol, netconsole, weird behaviour in suspend/resume) are solved 
I'll convert the whole source to netdev_priv().

It seemed to me a waste of space, as the functions are so small and 
obvious.

Thanks for the feedback.
