See https://www.kernel.org/doc/Documentation/networking/i40e.rst, in particular, read the paragraph on "Unexpected Issues when the device driver and DPDK share a device".

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
