[dpdk-users] PMD: eth_ixgbevf_dev_init(): VF Initialization Failure: -15

[Sandeep Rayapudi]

Thanks Ori.
When I did the ip link up, packetgen comes up.

Now the nics on these two hosts connected by cable. When I played traffic
on one container using packetgen, the traffic doesn't reach the other
container.
Any clues why?
