-Subject: [PATCH] brcmfmac: use static superset of channels for wiphy
- bands
-
-The driver was constructing a list of channels per wiphy band
-by querying the device. This list is not what the hardware is
-able to do as it is already filtered by the country setting in
-the device. As user-space may change the country this would
-require updating the channel list which is not recommended [1].
-This patch introduces a superset of channels. The individual
-channels are disabled appropriately by querying the device.
