         and just stick the payload into an 802.11 frame.  I've seen
         captures that show frames of that sort.

         We also handle some odd form of encapsulation in which a
         complete Ethernet frame is encapsulated within an 802.11
         data frame, with no 802.2 header.  This has been seen
         from some hardware.

         On top of that, at least at some point it appeared that
         the OLPC XO sent out frames with two bytes of 0 between
         the "end" of the 802.11 header and the beginning of
         the payload.

         So, if the packet doesn't start with 0xaa 0xaa:

           we first use the same scheme that linux-wlan-ng does to detect
           those encapsulated Ethernet frames, namely looking to see whether
           the frame either starts with 6 octets that match the destination
           address from the 802.11 header or has 6 octets that match the
           source address from the 802.11 header following the first 6 octets,
           and, if so, treat it as an encapsulated Ethernet frame;

           otherwise, we use the same scheme that we use in the Ethernet
           dissector to recognize Netware 802.3 frames, namely checking
           whether the packet starts with 0xff 0xff and, if so, treat it
           as an encapsulated IPX frame, and then check whether the
           packet starts with 0x00 0x00 and, if so, treat it as an OLPC
           frame. */

         and just stick the payload into an 802.11 frame.  I've seen
         captures that show frames of that sort.

         We also handle some odd form of encapsulation in which a
         complete Ethernet frame is encapsulated within an 802.11
         data frame, with no 802.2 header.  This has been seen
         from some hardware.

         On top of that, at least at some point it appeared that
         the OLPC XO sent out frames with two bytes of 0 between
         the "end" of the 802.11 header and the beginning of
         the payload.

         So, if the packet doesn't start with 0xaa 0xaa:

           we first use the same scheme that linux-wlan-ng does to detect
           those encapsulated Ethernet frames, namely looking to see whether
           the frame either starts with 6 octets that match the destination
           address from the 802.11 header or has 6 octets that match the
           source address from the 802.11 header following the first 6 octets,
           and, if so, treat it as an encapsulated Ethernet frame;

           otherwise, we use the same scheme that we use in the Ethernet
           dissector to recognize Netware 802.3 frames, namely checking
           whether the packet starts with 0xff 0xff and, if so, treat it
           as an encapsulated IPX frame, and then check whether the
           packet starts with 0x00 0x00 and, if so, treat it as an OLPC
           frame. */
