How to enable DFS channels?

[John Paul Morrison]

I am not able to see or connect to SSIDs on DFS channels with the b43
or wl Broadcom drivers - is there any way to enable these channels?

I can connect to normal 5 GHz channels and 2.4 GHz but not DFS ones
even though I've set the country code. I can see DFS channels with
other non Broadcom wifi adapters.

thanks
