[dpdk-dev] Ask help for mlx5 pmd driver

[benli ye]

Hi,

Could you please help me on mlx5 pmd driver? I have two mlx5 driver powered NICs (eth0 and eth1) and one is conneted to internet and the other is connected to intranet.
I want to use linux kernel net stack tool like bird app to send ospf packets and use ssh to login. But when I run the dpdk app and mlx5 pdm driver is working, the host is unreachable.
Do I need to use rte_kni to create another two interface maybe called eth2 and eth3 to connect kernel stack? Any suggestions?

Thanks very much!

Bests,
Daniel Benli Ye

Hi Benli,

Next time please send questions like this to dpdk-users mailing list, which
suits more these type of question.
Can you please share more info:
which dpdk app do you run ? Is it something you developed by yourself ?;

With Mellanox PMDs, you do not need to bind them to DPDK, as opposed to
other PMDs, because of the bifurcated model.

When you launch the application, do you pass two pci ids (with 2 "-w" EAL
argument), or only one , or none ?
