Subject: [PATCH] brcmfmac: use provided channels for scheduled scan
|
|
|
|
User-space can provide list of channels in the schedule scan request.
|
|
This was ignored so all channels supported and allowed by the device
|
|
were used. This patch configures the device to use the channels as
|
|
listed in the request.
