How's this: --- CALLING CRDA -- UDEV ====================== Distributions can set up a udev rule to allow the kernel's regulatory domain change request to be reviewed by CRDA so CRDA can pass an appropriate regulatory domain. An example regulatory rule is provided with this package as regulatory.rules --- Or the giant diagram here: http://wireless.kernel.org/en/developers/Regulatory This also mentions: --- CRDA CRDA is our userspace agent which uploads regulatory domains into the kernel, it acts as a udev helper. --- Then the CRDA section on the CRDA page has a section: http://wireless.kernel.org/en/developers/Regulatory/CRDA#LettingthekernelcallCRDA We also have iw's documentation: http://wireless.kernel.org/en/users/Documentation/iw#Updatingyourregulatorydomain The wiki is editable by everyone so feel free to update that, and also feel free to send patches to the README as you see fit.
