      public static Dot11HtControl newInstance(byte[] rawData, int offset, int length) throws IllegalRawDataException
      A static factory method. This method validates the arguments by ByteArrays.validateBounds(byte[], int, int), which may throw exceptions undocumented here.
      Parameters:
      rawData - rawData
      offset - offset
      length - length
      Returns:
      a new Dot11HtControl object.
      Throws:
      IllegalRawDataException - if parsing the raw data fails.
