This is used to be able to send the channel switch announcements that
are queued from userspace out, yet not send dataframes in this same
queue out. This is to avoid exceeding regulatory requirements for
transmission time after radar has been detected.

It's not ideal, but possibly neither is hanging on to the frames
during the interval in which the channel changes hoping to find the
same station there.

Thanks,
