Please elaborate on the motivation: What is your interest in CFM? Are
you using it in production? Does anyone? Who needs this in iproute2?
What is missing from Microchip's cfm tool?

Looking at the kernel log, since CFM was merged six years ago, no new
features were added and the only bug fixes are for issues found by
static checkers and LLMs with no reviews from the original authors.
There are also no selftests.

If nobody cares about CFM or uses it, then I would prefer to start
deprecating it instead of accumulating more code that needs to be
maintained and that nobody is going to use.
