Or,
I've got a rough patch to use rtnl_link_ops to add what we've been
calling 'virtual machine device queues' or VMDq. This looks a lot
like macvlan with offloaded switching and I believe similar to your
child case above.
Also what is a "pkey"
I'll post it as a use at your own risk shortly although this week I'm
short on time so maybe next week I can get something more "real" out.
Been stealing cycles between other work things today.
If you want to do complete it more power to you.
