I think you should use a more specific command name.

quoted

+		goto nla_put_failure;

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

quoted

+	if (data->channel)
+		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


Also the indentation in the documentation didn't match the convention
used there.

Looks like there are two conventions used (see HWSIM_CMD_TX_INFO_FRAME,
and HWSIM_CMD_NEW_RADIO).  I guess you want it indented like the NEW_RADIO
command?

Thanks,
