[dpdk-users] DPDK 17.05 does not find X510 card

[Martin Drašar]

Hello,

I have a CentOS 7 system with two 2-port X710 cards:

> [root at dhcp13-55 pain]# lspci -nn | grep X710

According to tth 17.05 release notes, the cards should work. However,
when I run the dpdk_init(), cards are not identified, and
rte_eth_dev_count() returns 0.

Do you have any idea, what may be the cause or how should I proceed to
debug it?

Thank you,
Martin
