In the decompression mode, the signal m_axis_tuser[35:32]
indicates error in the GZIP/ZLIB compressed file format. If
any of the bits go high, this indicates that there is an error in the header section of the
GZIP/ZLIB compressed file. If you get this error, you can reset the core and run it again
with the modified compressed file. For more information on GZIP/ZLIB compressed file
formats, see these links RFC-1950, RFC-1951, RFC-1952.
