Hi, Wenjia. I agree with your concerns.

My initial intention is to make these proc files serve as a supplement to netlink to conveniently
check smc connections in an environment where smc-tools cannot be easily obtained.

Yes, proc files won't be the first choice for diagnosis, but can be a convenient backup.

Wen Gu
