Merging the conversations about both of these RFCs since my comments and questions are the same for both. What is the motivation for adding support for these RFCs? Is the push from a company or academia (e.g., a CS project)? Realistically, who is expected to use this feature and why given the information it leaks about the networking configuration of the node. Why is this tool expected to be more useful than a network operator using existing protocols like lldp, collecting that data across nodes and analyzing, or using tools like suzieq[1]? RFC 5837 has been out for 11 years. Do any operating systems support it — e.g., networking vendors like Cisco, Juniper, etc.? If not, why not? This one seems to me the most dubious at this point in time. Similarly for RFC 8335, what is the current support for it? Linux does not need to support an RFC just because it exists. I am really questioning the value of both of them [1] https://github.com/netenglabs/suzieq
