[dpdk-dev] Port Link Down Error while ruining Dpdk ipsec-secgw application

[satyavalli rama]

Hi Anoob and DPDK Dev Team,

Please guide us resolve the issue..

While running the ipsec-secgw application the ports are getting down and it
is throwing

------>Port Link Down Error

We are doing the below steps:

Since we don't have IXGBE driver in the virtual machines. we used SRIOV to
import the IXGBE NIC's (Virtual function) from host(Physical function).
We refered the below link for SRIOV:
https://software.intel.com/content/www/us/en/develop/articles/configure-sr-iov-network-virtual-functions-in-linux-kvm.html

This the info after importing IXGBE NIC's into virtual machine:
