I have reviewed this document as part of the IntArea directorate's ongoing
effort to review all IETF documents being processed by the IESG. These comments
were written primarily for the benefit of the internet area directors. Document
editors and WG chairs should treat these comments just like any other last call
comments.

Overall this draft was well written and very useful not only from ops view but
from the int-area point of view as well, suppress-flapping, dampening to make
network stable.

Nits:
- The lower/higher-layer-if definitions in RFC8343 would need to be better to
clarify the differences between sub-interface defined in this draft.

- How the module can manage linux networking abstraction for example, bridge,
vrf interfaces would be better to mention in somewhere, like if a vlan
interfaces has one parent ethernet interface, the vlan interface also have the
bridge or vrf interface as another parent (or master). Please check whether the
module support that or not.

- A peer-interface of an interface pair would usually be associated to a netns.
It would be better to mention that, and would be better to make the module to
be able to do that.
