Set hardware iface state for loopback interfaces
So unless I have missed something, loopback interfaces are spawned hardware-down and never set up. This patch uses the same process as tapcli interfaces by mirroring sw state to hw state. Change-Id: I94198c1c880de773daccbb63ca8d32c4c7e26a74 Signed-off-by: Pierre Pfister <ppfister@cisco.com>
