Openstack SRIOV Enablement in Intel X710 NIC

To enable SDN Assist, we are unable to enable SRIOV in our Openstack infrastructure.

NIC: Intel X710 Openstack Version : Pike for intel X710 NIC disable i40evf driver rmmod i40evf blacklist the driver: /lib/modprobe.d/blacklist_linux_4.4.0-131-generic.conf add: #i40evf driver blacklist i40evf

Steps:

enable SRIOV and Vitualization in BIOS
