I got the number after a reboot, not sure what happened.
And I also feel surprised... But the result shows the number, so I have
to put it here.

For bridge testing I use ethtool_stats.pl. For later xdp_redirect_map
and xdp_redirect_map_multi testing, I checked that ethtool_stats.pl and
XDP program shows the same number. When run ethtool_stats.pl the number
will go a little bit slower. So at the end I use the xdp program's number.

I'm going to re-setup the test environment and share it with you. Hope
we could get a final number that we all accept.

Thanks
