I tried it briefly, and it works for the handful of testcases
that I tried, but I still think its very werid to register
as both a device and a subsys, esp in the light of the 
warning in net_namespace.h

Thus I have to spend some time reviewing your patch,
and I cannot give you an answer in the next 5 minutes.

So you are saying there are scaling constraints on subsystems
that register for netdevice handlers. The disturbing part
of that is that it does not scale.

Thanks.
