Yes, this disable 5GHz for 3945. I assumed this is not and will not be
used anymore, but seems I was wrong.

BTW: I'm not expect that 11ac AP will work good with 11a, i.e. I'm not
able to connect to mixed network 11a & 11n on my 5GHz AP, but at least
this should be theoretically possible. 

What I'm looking for is possibility to disable 5GHz to avoid network
traffic delays while scanning, but this should be done in cfg80211.

Let's skip this patch.

Thanks
