All sorts of childs are still created/deleted through sysfs, in a
similar manner to the way legacy child interfaces are.

Network device instantiation of this type is the domain of
rtnl_link_ops rather than ugly sysfs interfaces.

Didn't add any **new** sysfs interfaces in this patch. The IPoIB sysfs
entries to create child devices are there from IPoIB's day one, and
we're only extending them a tiny bit.

That's extremely unfortunate, having private ways of instantiating
networking devices leads to an extremely poor user experience.

Would you like to have to train every single user in the case
where each and every driver author makes his own unique way
of configuring his hardware?

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.
