README: add legacy notice
|
||
|
|
|

|
|
As if kernel v4.15 CRDA is no longer needed. Annotate this. The

|
|
code will still be maintained to help older kernels.

This is the Central Regulatory Domain Agent for Linux. It serves one

-purpose: tell Linux kernel what to enforce. In essence it is a udev
|

|
|
-helper for communication between the kernel and userspace. You only
|

|
|
-need to run this manually for debugging purposes. For manual changing
|
||
|
|
-of regulatory domains use iw (iw reg set) or wpa_supplicant (feature
|

|
|
-yet to be added).
