parentnetdev: Create netdev_queue abstraction. (diff)

pkt_sched: Remove 'dev' member of struct Qdisc.
It can be obtained via the netdev_queue. So create a helper routine, qdisc_dev(), to make the transformations nicer looking. Now, qdisc_alloc() now no longer needs a net_device pointer argument. Signed-off-by: David S. Miller <davem@davemloft.net>
