useful.
Let's assume you want to save power on turn off WiFi if you are temporarily
not using it.
init/deinit are not useful for this purpose.
I can imagine driver specific commands as well, but the ability to pass any
command will solve this issue.
Thanks,
Dmitry

</div>Would you be able to describe what kind of functionality this is used<br>
for? Are these truly driver specific or could there be more generic use<br>

</div>I would assume this depends on what the exact functionality would be. I<br>
could imagine some driver interaction to be perfectly reasonable to do<br>
directly from an external application at least when the operations are<br>
completely independent from the normal supplicant functionality (e.g.,<br>
WMM configuration) while some operations are likely to fit better with<br>
wpa_supplicant talking to the driver in order to avoid conflicts with<br>
other wpa_supplicant-initiated commands.<br>
<br>
As far as the source code change itself is concerned, yes, I would<br>
expect that an additional command in ctrl_iface.c and a handler function<br>
in struct wpa_driver_ops would be the cleanest way of doing this for<br>
driver specific changes.<br>
