What is the "preferred frequency" referring to here? If that is any
frequency, the design below does not really work in general.

Why? That chan_freq is most likely not the starting frequency of the
channel, but a center frequency of a 20 MHz channel that is within the
full frequency range. That would also imply that chan_freq + bw might be
beyond the end frequency of the channel.
