[net-next,v3,0/3] virtio-net: synchronize op/admin state

Message

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.

Changes since V2:

- introduce config_driver_disabled and helpers
- schedule config change work unconditionally

Jason Wang (3):
  virtio: rename virtio_config_enabled to virtio_config_core_enabled
  virtio: allow driver to disable the configure change notification
  virtio-net: synchronize operstate with admin state on up/down
