This is the first in a series of functions that aims to copy forward interface changes in the VPP dataplane into the linux interfaces. Capture link state changes (set interface state ...) and apply them to Linux. There's an important dissonance here: - When Linux sets a parent interface up, all children also go up. ip link set enp66s0f1 down ip link add link enp66s0f1 name foo type vlan id 1234 ip link set foo down ip link | grep enp66s0f1 9: enp66s0f1: <BROADCAST,MULTICAST> mtu 9000 qdisc mq state DOWN mode DEFAULT group default qlen 1000 61: foo@enp66s0f1: <BROADCAST,MULTICAST,M-DOWN> mtu 9000 qdisc noop state DOWN mode DEFAULT group default qlen 1000 ip link set enp66s0f1 up ip link | grep s0f1 9: enp66s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc mq state UP mode DEFAULT group default qlen 1000 61: foo@enp66s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 qdisc noqueue state UP mode DEFAULT group default qlen 1000 While in VPP this is not so, there each individual interface and sub-interface stands for itself. I think the proper fix here is to walk all sub-interfaces when a phy changes, and force a sync of those from VPP to LCP as well. I'll do that in a followup commit so it's easier to roll back.
