Unfortunately, question has no info about what is the DPDK version running.

Be sure you are using lates 20.11.3 (LTS) and if the issue is still happens, test if it present in 21.05 and 21.08

If you were able to run testpmd before, what is different between now and then?

Hi, Thanks for the response. dpdk-testpmd works with 20.11.3 from dpdk-stable. Previous offending version was 20.11 and worked until firmware upgrade. One additional question on l2fwd-nv. The program fails with message with the message not being able to parse the device:

./l2fwdnv -l $LCORES --main-lcore=$(echo $LCORES | sed -e ‘s/(.).*/\1/g’) -a $MLX_PCIEADDR,txq_inline_max=0 #-- -m 1 -g0 -w 3 -P 0 -b 64 -B 1 -c 1 -d 9216

EAL: Unable to parse device ‘0000:b5:00.1,txq_inline_max=0’

EAL: Error - exiting with code: 1

Cause: Invalid EAL arguments

Let me know to submit a new case if need be.

Glad to hear original issue solved.

Regarding second question, create a new post with adding extended command line in such way that instead of “echo XXX| sed YYY” and MLX_PCIEADDR there will be a real content.

Why there is an “#” on the command line?

Thanks will open a new case.
