Hi,
I don't see any point in sending peer_ifindex through ethtool, even
worse through ethtool stats. That is definitely the wrong place for it.
You can already retrieve that through netlink. About the speed/duplex
this one makes more sense, but this is the wrong way to do it.
See how we did it for virtio_net (you are free to set speed/duplex
to anything to please bonding for example). Although I doubt anyone will 
use netkit with bonding, so even that is questionable. :)
