Hi dpdk-users!

I have some new 25G cards:
Intel Corporation Ethernet Network Adapter XXV710-2

I am using the latest i40e driver

filename:
/lib/modules/3.10.0-862.11.6.el7.x86_64/updates/drivers/net/ethernet/intel/i40e/i40e.ko
version:        2.4.10
license:        GPL
description:    Intel(R) 40-10 Gigabit Ethernet Connection Network Driver
author:         Intel Corporation, <e1000-devel@lists.sourceforge.net>
retpoline:      Y

When I try to do dpdk-devbind I get the following error

Error: bind failed for 0000:05:00.0 - Cannot bind to driver uio_pci_generic

This shows in dmesg
[240097.901062] i40e 0000:05:00.1: removed PHC from ens2f1
[240097.966118] i40e 0000:05:00.1: Set default VSI failed, err
I40E_ERR_ADMIN_QUEUE_ERROR, aq_err I40E_AQ_RC_EINVAL
[240097.966122] i40e 0000:05:00.1: Setting promiscuous on failed on PF, err
I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_EINVAL

I am moving from some much older 1G cards I had, but they were binding ok,
however it was the igb driver.

I can seem to find much, I guess these are quite new cards and the driver
is up to date as well, a bug maybe?

Thanks

Roland
