    ieee802154: support multipurpose frames
    
    Add support for IEEE802.15.4-2015 multipurpose frames, which are
    similar to data frames with the following exceptions:
     - The Frame Control Field can be either 1 or 2 octets, with different
       bit offsets for all fields except for Frame Type.
     - The Frame Version field, when present, must always be set to 00.
     - The source PAN ID is always absent
     - Instead of a PAN ID Compression field, there is a PAN ID Present
       field for the destination PAN ID only.
    
    See Section 7.3.5 of IEEE802.15.4-2015 (esp Figure 7-19) for details.
