Re: Survey dump does not seem to work with SONY USB Wireless LAN Adapter UWA-BR100

Sujith,

Appreciate the quick response.
Is there a plan to add this functionality in ath9k_htc driver?
If yes, it would be great if you can share a tentative date by when
this functionality will be available.
If no, then is there any other way of retrieving this information.

Thanks once again.
