4855 and just stick the payload into an 802.11 frame. I've seen
4856 captures that show frames of that sort.
4857
4858 We also handle some odd form of encapsulation in which a
4859 complete Ethernet frame is encapsulated within an 802.11
4860 data frame, with no 802.2 header. This has been seen
4861 from some hardware.

4864 the OLPC XO sent out frames with two bytes of 0 between
4865 the "end" of the 802.11 header and the beginning of
4866 the payload.
4867

4869
4870 we first use the same scheme that linux-wlan-ng does to detect
4871 those encapsulated Ethernet frames, namely looking to see whether
4872 the frame either starts with 6 octets that match the destination
4873 address from the 802.11 header or has 6 octets that match the
4874 source address from the 802.11 header following the first 6 octets,
4875 and, if so, treat it as an encapsulated Ethernet frame;
4876
4877 otherwise, we use the same scheme that we use in the Ethernet
4878 dissector to recognize Netware 802.3 frames, namely checking
4879 whether the packet starts with 0xff 0xff and, if so, treat it
4880 as an encapsulated IPX frame, and then check whether the
4881 packet starts with 0x00 0x00 and, if so, treat it as an OLPC

15142 and just stick the payload into an 802.11 frame. I've seen
15143 captures that show frames of that sort.

15145 We also handle some odd form of encapsulation in which a
15146 complete Ethernet frame is encapsulated within an 802.11

15151 the OLPC XO sent out frames with two bytes of 0 between
15152 the "end" of the 802.11 header and the beginning of
15153 the payload.
15154
15155 So, if the packet doesn't start with 0xaa 0xaa:
15156
15157 we first use the same scheme that linux-wlan-ng does to detect
15158 those encapsulated Ethernet frames, namely looking to see whether
15159 the frame either starts with 6 octets that match the destination
15160 address from the 802.11 header or has 6 octets that match the
15161 source address from the 802.11 header following the first 6 octets,
15162 and, if so, treat it as an encapsulated Ethernet frame;
15163
15164 otherwise, we use the same scheme that we use in the Ethernet
15165 dissector to recognize Netware 802.3 frames, namely checking
15166 whether the packet starts with 0xff 0xff and, if so, treat it
15167 as an encapsulated IPX frame, and then check whether the
15168 packet starts with 0x00 0x00 and, if so, treat it as an OLPC
