Channel numbers of 6G band overlaps with those of 2G or 5G bands.
Therefore, an optional argument "6G" is added and expected next
to channel number to map it to correct 6GHz frequency. If not
specified, defaults to matching 2G or 5G frequency.

example:
iw wlanX set channel 149 6G 80MHz  --> maps to 6695 MHz
iw wlanX set channel 149 80MHz     --> maps to 5745 MHz

Hm. I can't really say I like this much.

Is it _really_ needed? I mean, we mostly specify the frequency today, so
... why not just always do that for 6 GHz?

I suspect there are people preferring channel numbers as much as there 
are people preferring frequencies. Personally, I think it is acceptable 
to put this limitation on 6G.
