Great! A test would be nice because I have just did basic tests: mainly an
iperf.

I can revert this change, initially I moved this chunk because I wanted
to add a netdev_ops before registering it and this netdev_op depend on
the bm support. As for now I don't have this this netdev_op this change
is pointless. But if in future I need it, then I will look for how to do
it in a different way.

Thanks,
