Hi all, We got a bunch of X710 NIC and cant use them with our custom app. As the topic says, rte_eth_dev_count returns 0. And after a quick investigation with testpmd, we saw that i40e_aq_get_phy_capabilities returns 'I40E_ERR_UNKNOWN_PHY'.
The tests are performed on a Xeon server with double numa on a Debian/jessie. Both 16.11.2 and 17.05.1 versions of DPDK were tested. The SFP useds are Intel FTLX1471D3BCV-IT. Here are the logs of dpdk-devbind:

We init EAL with these params:

Some demsg logs:

We searched clues on internet, find [1] but did not help, then came to the IRC channel, where Christian Ehrhardt point us to [2]. We are still making tests, but for sure, if we plug a port to another upped link, testpmd succeed to detect the port (nevertheless, on our app rte_eth_dev_count still returns 0). So, we assume that our issue is related to [2]. Any help will be welcome. :) Thanks in advance, [1] : http://dpdk.org/doc/guides/nics/i40e.html [2] : [dpdk-dev] i40e_aq_get_phy_capabilities() fails when using SFP+ with no link http://dpdk.org/ml/archives/dev/2017-January/055617.html Jonathan.
