I would rather see SET_NETDEV_DEV go away. It was done for source
compatibility between 2.4 and 2.6 network device drivers. This is
no longer really important.
It would be better to either access the network device directly.
BUT, there are plans to get rid of class_dev so that would mean
source changes to all the drivers again...
So how about these wrappers.
