ipvlan: handle NETDEV_DOWN event
In case of stacked devices, to help propagate the down
link state from the parent/root device (to this leaf device),
handle NETDEV_DOWN event like it is done now for NETDEV_UP.
In the below example, ens5 is the host interface which is the
parent of the ipvlan interface eth0 in the container.
Host:
[root@gkn-podman-x64 ~]# ip link set ens5 down
[root@gkn-podman-x64 ~]# ip -d link show dev ens5
3: ens5: <BROADCAST,MULTICAST> mtu 9000 qdisc mq state DOWN
...
[root@gkn-podman-x64 ~]#
Container:
[root@testnode-ol8 /]# ip -d link show dev eth0
2: eth0@if3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 state UNKNOWN
...
ipvlan mode l2 bridge
...
[root@testnode-ol8 /]#
eth0's state continues to show up as UP even though ens5 is now DOWN.
For macvlan the handling of NETDEV_DOWN event was added in
commit 80fd2d6ca546 ("macvlan: Change status when lower device goes down").
