Actually this is not as bad as it sounds.  Since you're constructing
the hardware header anyway, it may turn out to be easier to tack on
the Ethernet header while you're at it.

Please note that the hardware cache is not the same as the neighbour
cache.  Just because you lose the hardware cache doesn't mean that
you'd lose the neighbour (ARP) cache.

However, this would mean that you'd no longer have an Ethernet device
which is both good and bad.

Cheers,
