Re: [dpdk-users] SR-IOV problem with dpdk drivers

I’m not an expert, but my guess is that your PF is running a very different version of the i40e driver, and because of this the two cannot communicate. I personally have never seen this before. Perhaps google has?

Is the igb_uio kernel module loaded? lsmod should say. If not, run 'modprobe igb_uio', then try again.
