            The problem happens because ha_tina write data to the CSV file using text notation for INET6:

            "2001:db8::ff00:42:8329"

            but when it further reads a row in this statement:

                  if ((*field)->store(buffer.ptr(), buffer.length(), buffer.charset(),
            		 
                                      is_enum ? CHECK_FIELD_IGNORE : CHECK_FIELD_WARN))

            Field_inet6::store() considers the data to be in the binary format, because buffer.charset() points to &my_charset_bin.
