The MacSupportFlags are being decoded improperly.  This may have to do with
big/little endian decoding.  All the numeric fields in this structure are
little endian.  Refer to the SNIA CIFS Reference.

The note in the spec about big endian only applies to the Finder Info field,
and not to other items in the structure.

The attached trace should indicate Macintosh and Streams extensions NOT
supported (0x100).
