Hello,


I have some questions regarding the i40e driver in reference to Intel X710 NICs.


I have several 10G X710 cards on a host, mapped into a kvm-based guest via PCI-passthrough.


DPDK sees these cards (the 6 in "Other Network Devices"):

# dpdk-devbind --status

Network devices using kernel driver
===================================
0000:00:03.0 '82540EM Gigabit Ethernet Controller 100e' if=eth0 drv=e1000 unused=uio_pci_generic
0000:00:04.0 'Virtio network device 1000' if=eth1 drv=virtio-pci unused=uio_pci_generic

Other Network devices
=====================
0000:00:09.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=uio_pci_generic
0000:00:0a.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=uio_pci_generic
0000:00:0b.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=uio_pci_generic
0000:00:0c.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=uio_pci_generic
0000:00:0d.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=uio_pci_generic
0000:00:0e.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' unused=uio_pci_generic

No 'Crypto' devices detected
============================

No 'Eventdev' devices detected
==============================

No 'Mempool' devices detected
=============================

No 'Compress' devices detected
==============================

But it wont bind them to the i40e driver:

root@10.129.182.229:~# dpdk-devbind -b i40e "0000:00:09.0"
Error: bind failed for 0000:00:09.0 - Cannot bind to driver i40e

I'm wondering what I can do to debug this?

Thanks,
Jeff
