read the paragraph on "Unexpected Issues when the device driver and DPDK share a device".

Subject: [dpdk-dev] Need Help for Intel - i40e , XL710 40GbE Controller

Hi,
I am using  XL710 40GbE Controller with two ports.
The way I am using them is one port is configured to vfio-pci for using
with dpdk in user space and the other is left to the kernel driver and for
a seperate application that does not use DPDK.
As soon as DPDK initialize and start the port, the other port
become unusable.

Is there any setting/configuration that I am missing  ?

Thanks,
Avner
