RE: e1000 performance hack for ppc64 (Power4)

Scott, would you be pleased if something was implemented out 
of the driver, in generic net code?  Something that all the 
drivers could use, even if nothing but e1000 used it for now.

I suppose the driver could unconditionally call something like
skb_realign_for_broken_hw, which is a nop on non-broken archs, but would
it make more sense to not have the driver mess with the skb at all?
