dpdk-testpmd works but dpdk pktgen crashes on startup with MLX5 card

[Antonio Di Bacco]

If I try to use dpdk-pktgen on a MLX5 card, I get this SIGSEGV

[user at dhcp-10-84-89-229 pktgen-dpdk]$  sudo
LD_LIBRARY_PATH=/usr/local/lib64 ./usr/local/bin/pktgen -l50-54  -n 2

Testpmd works fine on the same card.

Anyone can give me a suggestion?

Best regards.
