John-
      Sorry for not copying your orgional patch into your email, but I apparently
erased this email prior to fully reading it.  At any rate, as we discussed the
other day, I think this idea is great, but it would benefit from being
implemented using macvlans rather than a new link type.  If we can set a
hardware flag in the underlying driver to indicate support for hardware
forwarding, we can skip the macvlan soft forwarding, and just transmit directly.
It should save us needing to create a whole new link type that is so simmilar to
one we already have.

      I'm back home now, so I can start looking at this if you like on monday.

Yes definitely take a look making it an extension (flag) to macvlan
would be more useful if it can work. The one question I have is would
we need to clear the flag when a feature is attached to the PF that can
not be done in hardware. For example attaching an ingress qdisc,
ebtables, or starting up tcpdump are two that come to mind.

Sorry for the duplication Neil, I sent this mail from a broken email
client just a minute ago and vger dropped it.
