The CAC times are currently hard-coded in the kernel. The new
regulatory db framework (loading it as a firmware file) has the ability
to provision it through there, but the wireless-regdb db.txt, parser &
generator doesn't support it yet.

CRDA is more or less dead - still used, but will not get any future
work.
