This patch synchronize operstate with admin state per RFC2863.
This is done by trying to toggle the carrier upon open/close and
synchronize with the config change work. This allows propagate status
correctly to stacked devices like:
ip link add link enp0s3 macvlan0 type macvlan
ip link set link e
Sometime, it would be useful to disable the configure change

Hi All:
This series tries to synchronize the operstate with the admin state
which allows the lower virtio-net to propagate the link status to the
upper devices like macvlan.
This is done by toggling carrier during ndo_open/stop.

- introduce config_driver_disabled and helpers
