[dpdk-users] Problem with dpdk vf pollmode driver - Ethernet controller: Intel Corporation XL710/X710 Virtual Function

[Venumadhav Josyula]

Hi All,

We have SR-IOV, we have few virtual functions mapped to an vm. We have
seeing link issues, after we started dpdk based application we are seeing
following
