Why so? The old static regulatory domain definition for countries in-kernel are left intact from what they were originally defined by whoever it is that implemented that originally. They were just ported over to the new framework. This information is outdated and will be removed eventually, this is why it falls under OLD_REG kconfig option. > 2) Why only 3 static reg domains where chosen? Because the approach we decided to take was to not define country regulatory domains in-kernel anymore and instead move the definitions to userspace. The 3 static regulatory domains for US, EU and JP are purely historical. If you want to look at the *current* regulatory framework look at the code and ignore the OLD_REG crap, which will eventually be removed.
