Hi,
OS: CentOS 7.5.1804
Pktgen version: pktgen-3.5.8
DPDK verison: dpdk-18.08
I use the pktgen in follows command. When I start pktgen, default PktSize is 64, in the command I sad:
./pktgen -l 0-4 -n 3 -- -P -m "[1:3].0,[2:4].1"
Pktgen:/> start all
Link State : <UP-1000-FD> <UP-1000-FD> ----TotalRate----

Runts/Jumbos : 8889515/0 8913610/0
Errors Rx/Tx : 0/0 0/0
......< shown parts of pktgen >.....
Then will be get Runts.
I tried when size is 68, range will be in [64 Bytes], and no runts.
Pktgen:/> set 0 size 68
Pktgen:/> set 1 size 68
Pktgen:/> start all
I guess it may related about range, could help to check?
Thanks.
Best regards,
Bichan.Lu

Follow is command and result: By the way, it seems there is no conditional expressions to check whether support crc-strip or not, when set pktgen size? Will you add after? Because --crc-strip only check Pkts receive, it seems mismatch. ./pktgen -l 0-4 -n 3 -- -P --crc-strip -m "[1:3].0,[2:4].1" Pktgen:/> start all \ Ports 0-1 of 2 <Main Page> Copyright (c) <2010-2018>, Intel Corporation Flags:Port : P--------------:0 P--------------:1 Link State : <UP-1000-FD> <UP-1000-FD> ----TotalRate---- Pkts/s Max/Rx : 1487850/1487850 1491605/1491605 2979455/2979455 Max/Tx : 1491605/1491605 1487850/1487850 2979455/2979455 MBits/s Rx/Tx : 999/1002 1002/999 2002/2002 Broadcast : 0 0 Multicast : 0 0 64 Bytes : 3117320 3126509 65-127 : 0 0 128-255 : 0 0 256-511 : 0 0 512-1023 : 0 0 1024-1518 : 0 0 Runts/Jumbos : 0/0 0/0 Errors Rx/Tx : 0/0 0/0 ......< shown parts of pktgen >.....
