Actually this is not as bad as it sounds.  Since you're constructing

the Ethernet header while you're at it.

We actuall remove the ethernet header and rewrite it to a hardware
header as the 802.11 spec pretty much mandates.

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.

Ok.

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

Yeah. I don't think that'll go down well with userspace.
