* <channel>: channel number of the 10MHz or 20MHz channel,

* <band>: A for 5GHz, B for 2.4GHz
* <bandwidth>: N for 10MHz, nothing for 20MHz or 40MHz
* (ctl-sideband spec implies 40MHz)
* <ctl-sideband>: U for upper, L for lower

* <band> may be omitted on input, and will be assumed to be
* 2.4GHz if channel number <= 14.

* Examples:
* 8 -> 2.4GHz channel 8, 20MHz
* 8b -> 2.4GHz channel 8, 20MHz
* 8l -> 2.4GHz channel 8, 40MHz, lower ctl sideband
* 8a -> 5GHz channel 8 (low 5 GHz band), 20MHz
* 36 -> 5GHz channel 36, 20MHz
* 36l -> 5GHz channel 36, 40MHz, lower ctl sideband
* 40u -> 5GHz channel 40, 40MHz, upper ctl sideband
