14 Keeping regulatory domains in userspace
17 Due to the dynamic nature of regulatory domains we keep them
19 to the kernel one regulatory domain to be used as the central
20 core regulatory domain all wireless devices should adhere to.
22 How to get regulatory domains to the kernel
25 When the regulatory domain is first set up, the kernel will request a
