Hello.

I found some problem with virtio xstats counters.

Example:

rx_good_packets: 3
rx_good_bytes: 180
rx_errors: 0

rx_q0_good_packets: 3
rx_q0_good_bytes: 180
rx_q0_errors: 0

rx_q0_multicast_packets: 3
rx_q0_broadcast_packets: 1
rx_q0_undersize_packets: 3

It means that undersize packets are counted as good packets instead of errors. Or maybe size of packet is calculated wrong.
I don't have time now to check it more deeply - I can do it sometime later, but maybe someone want to help.

PS. Is it a common practice to count broadcast packets twice - in broadcast and multicast counters?

Best regards,
Igor
