Thanks, applied with some fixes:

I'd assume this comparison was supposed to use the channel argument to
the function instead of iface->conf->channel to make this work with
secondary channel.

And this needs to calculate the actual secondary channel since
iface->conf->secondary_channel is -1, 0, or 1.
