Wrong Total-rx-pkt about trex-core HOT 3 CLOSED

please provide more information

from trex-core.

"Trex always shows one more packets total_rx than total_tx
When I ran trex, I see that one packet (64 bytes) at the beginning of the test which considered at the total-rx statistics that make we always have one more packet rx than tx.
let me show a scenario:
i have ran the following command:
./t-rex-64 -c 1 -d 1 -m 1 -f cap2/dns_no_delay.yaml
the statistics that i see is:
Total-pkt-drop : 0 pkts
Warning : number of rx packets exceeds 101% of tx packets!
Total-tx-bytes : 170 bytes
Total-tx-sw-bytes : 0 bytes
Total-rx-bytes : 234 byte
Total-tx-pkt : 2 pkts
Total-rx-pkt : 3 pkts
Total-sw-tx-pkt : 0 pkts
Total-sw-err : 0 pkts
Total ARP sent : 2 pkts
Total ARP received : 0 pkts
I ran command in a back to back configuration

Hi,
When I run your command on ports connected in loopback, I see the counters as below (which is OK). Is it possible that you have some switch in the middle which issues the extra ARP packet?

Total-pkt-drop : 0 pkts
Total-tx-bytes : 170 bytes
Total-tx-sw-bytes : 0 bytes
Total-rx-bytes : 170 byte

Total-tx-pkt : 2 pkts
Total-rx-pkt : 2 pkts
Total-sw-tx-pkt : 0 pkts
Total-sw-err : 0 pkts
Total ARP sent : 2 pkts
Total ARP received : 0 pkts
