This may be the first of several similar commits to do this throughout IPv6, 
but I think optimizations like this really belong in the network drivers; or 
at least at that level.  OTOH I'm not sure doing this is worthwhile at all.  
I'd be interested in real experiences to back this up.  FWIW I noticed that 
some Linux network drivers do this.
