macvlan: Change status when lower device goes down
Today macvlan ignores the notification when a lower device goes administratively down, preventing the lack of connectivity from bubbling up. Processing NETDEV_DOWN results in a macvlan state of LOWERLAYERDOWN with NO-CARRIER which should be easy to interpret in userspace. 2: lower: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 3: macvlan@lower: <NO-CARRIER,BROADCAST,MULTICAST,UP,M-DOWN> mtu 1500 qdisc noqueue state LOWERLAYERDOWN mode DEFAULT group default qlen 1000 Signed-off-by:Suresh Krishnan <skrishnan@arista.com> Signed-off-by:
