Seeing Keepalive Drop Packets when Running in ASTF Mode with UDP Protocol

[jeremy020]

Description

• With multi core: I'm seeing some packet drops when running trex in ASTF mode with UDP protocol. I tried with 1M CPS which gave me around 1600 keepalive packet drops. I'm also seeing this when running at a higher CPS.
• With single core: I'm seeing half of the transmitted packets are getting dropped due to the keepalive issue. Upon investigation, realized that half of the packets are going into queue 1 and the other half are going into queue 0; however, they should all go to queue 0.

TRex Configuration

To Reproduce

1. Start trex on one terminal by using ./t-rex-64 -c 8 -i --astf
2. Start trex-console on another terminal using ./trex-console
3. Then using this command start -f astf/udp1.py -m 10000000 -d 100 in trex-console
