      The ChannelSequence value is only recognized in request messages,
      and only if the dialect is 0x0300 or greater.  That is, this
      field does not not exist in SMB2.x, only in SMB3.x.  In all
      responses, and in dialcts prior to 0x0300, the bytes of this
      field are always seen as part of the Status field.
