WebIf the former then you should be able to use treeitem:add_packet_field with an encoding of ENC_LITTLE_ENDIAN to tell Wireshark to flip the bytes. Of course you'd want the ProtoField to be a ftypes.UINT16 and you'd presumably want to give it a mask of 0x7FF (so Wireshark will use only the lower 11 bits in calculating the value).
