In the same way as you create monitor devices.

It was a change pending since long ago.

Yes. SMAC = 0x7e 0xff <data...> <FCS>

I have a passion about autobinding. I'd prefer manual control over it.

No. This is totally unacceptable. One of the users of wpan device shan't
block other users. Moreover what about devices with several wpan
interfaces, where some of them should be 6lowpan, some of them should be
zigbee (BTW: kernel implementation of zigbee seems to be impossible due
to licensing agreements under which ZigBee Alliance provides
specifications).

Theoretically yes, you can mix them. No, you can't easily tell them
apart. The specified protocol handler should apply specific logic to
drop unacceptable packets.
