Message

Hi All:

Currently, we don't synchronize the opersteate with the admin state
currently when prevent the link status to be propagated to the stacked
device on top of the virtio-net.

This patch fixes this issue.

Changes since V1:
- Try to reuse the virtio core facility to enable and disable the
  configure interrupt

Jason Wang (3):
  virtio: allow nested disabling of the configure interrupt
  virtio: export virtio_config_{enable|disable}()
  virtio-net: synchronize operstate with admin state on up/down
