- Add a configuration option to disable 6GHz collocated scanning.
- Add a parameter to the manual scan command to disable 6GHz
collocated scanning.
These options can be used to disable 6GHz collocated scan logic.
Note that due to limitations on probe request transmissions mandated
in Draft P802.11ax_D8.0 it is very likely that non PSC channels
would be scanned passively.
