I think you should use a more specific command name.

and at least also add a more specific identifier like the radio ID.

+		center_freq = data->channel->center_freq;
+
+	if (nla_put_u32(skb, HWSIM_ATTR_FREQ, center_freq))
+		goto nla_put_failure;

and have the full channel definition

You want chandef.center_freq1,
	 chandef.center_freq2,
	 chandef.width?


Anything else?

The control channel center_freq is already there so that should be the
full chandef. I guess center_freq2 should be conditional on being non-
zero.

I posted a new patch series a day or two ago...please let me know
if that looks right to you.  I un-conditionally included freq2, but
I think that is cleaner code all around.  Still, I'll make it conditional
if that is important to you.

Thanks,
Ben
