Thank you for the information. Would you like to provide a patch?
If not, I can write up a patch and tag you as the reporter.

Unfortunately we currently only support one rule per band. I'm inclined
to add the VLP one so outdoor usage is allowed.

AFAIK Intel manages regulatory requirements in their firmware, so it is
unrelated to the database we maintain.
