*Defined in [fuchsia.factory.wlan/iovar.fidl](https://cs.opensource.google/fuchsia/fuchsia/+/main:sdk/fidl/fuchsia.factory.wlan/iovar.fidl;l=13)*
<p>Allows the factory testing tool to communicate to the firmware via the driver using
a pre-formatted command buffer to observe and/or control the WLAN hardware's behavior.</p>

</ul>
<ul>
<li>response <code>result</code> pre-formatted response data retrieved from firmware</li>
</ul>
