virtio: fix link up/down flag
Type: fix "set int state <interface> down" puts the virtio device link down. It will not put the link in "UP" state, when "set int state <interface up>" will be used again to change the interface admin up. This patch fixes it. To test: create tap set int state tap0 up set int state tap0 down sh hardware sh int set int state tap0 up sh int sh hardware Change-Id: I3c0e31539f8a2a1e40220e7fb57eedecf408f067 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com> (cherry picked from commit 529f0e97b6064039c500adce0d54b738954b2ffa)
