trex-console doesn't report xstats when len(values) doesn't match len(names)

[Civil]

In DPDK 23.03 (and later), it is possible that Length of xstats_name doesn't match lenth of xstats_values:

There is an assumption that 'xstat_names' and 'xstats' arrays are matched by array index: xstats_names[i].name => xstats[i].value

This is exactly what happens in my case:

trex>stats -x

stats - Length of get_xstats_names: 79 and get_port_xstats_values: 63

Simple workaround would be to do:

        names = self.names[:len(values)]
        if len(values) != len(names):
            raise TRexError('Length of get_xstats_names: %s and get_port_xstats_values: %s' % (len(self.names), len(values)))

And that would make stats -x working again even if you combine multiple generations of connectx cards:
