* Note: wlan_uap_domain_info() and wlan_uap_callback_domain_info() are the
* original function which handles this functionality. However, it does it
* through and IOCTL and its control flow will not work in our case. To
* elaborate, it first gets the channel number by sending a command to
* firmware. Then in the cmd resp handler to sends the domain info
* command. As per the current design of our driver we cannot send command
* from command resp handler. Hence, we have modified the control flow to
* suit our design. The wifi_get_uap_channel() function also helps us in
* this by updating pmpriv->uap_state_chan_cb.band_config and
* pmpriv->uap_state_chan_cb.channel.
*
* fixme: Need to check how ACS works with this.
