I don't think so -- I don't recall anyone ever asking before ;-)

FWIW, I think right now we need to simply query mac80211's oper_channel
somehow -- that'll be good enough until that goes away for real
multi-channel operation.

Using the channel that was set on the monitor interfaces like these
patches have done is obviously flawed because monitor interfaces have
absolutely no influence on the channel unless that's all there is.
