Description:
Write:
<channel> [<bpst offset>]
<channel>
to start beaconing on a specific channel, or stop
beaconing if <channel> is -1. Valid channels depends
on the radio controller's supported band groups.
to force a specific channel to be used when beaconing,
or, if <channel> is -1, to prohibit beaconing. If
<channel> is 0, then the default channel selection
algorithm will be used. Valid channels depends on the
radio controller's supported band groups.
<bpst offset> may be used to try and join a specific
beacon group if more than one was found during a scan.
Reading returns the currently active channel, or -1 if
the radio controller is not beaconing.

* Using a Reset Device IE is too heavyweight as it causes the device

*
* Instead, reset authenticated devices with a SetAddress(0), followed
* by a SetAddresss(AuthAddr).
*
* The Linux USB stack resets a port twice before it considers it
* enabled, so we have to detect and ignore that.
