Band config through "setband" command does not reflect in "RF Bands" attribute of WPS-IE

[Shanbhag, Sandeep]

On the dual band capable device the default band setting is "Auto" in which case the "RF Bands" attribute indicates both bands "2.4 and 5 GHz ".
Some devices like the latest mobile phones with Android version Lollipop provide an option for the end user to change the band settings.
When such device uses the "setband" command to configure the supplicant, the changes only reflect in the channels used for scanning both in the case of STA and P2P but band setting does not reflect in the "RF Bands" attribute of the WPS-IE (Enrollee and P2P).
For example, if the user selects "2.4 GHz only" only option the STA scanning or P2P discovery is done only in 2.4 GHz band, probe requests will be sent only in 2.4 GHz channels but the "RF Bands" would stills wrongly indicate both bands "2.4 and 5 GHz"

This option is a global option and when a particular band (2.4 or 5) is chosen it reduces the device from dual band to a single band device and hence the "RF Bands" attribute in WPS-IE of both standalone WPS-Enrollee and P2P should indicate the band setting.
Supplicant requires a modification to reflect the band setting.
