I have a I350 2x1GBe SR-IOV card and have setup dpdk so I can use the drivers supplied with a KVM environment on Centos 7. I can load the vfio-pci driver for the VF nics. However at at 500Mbits/s UDP traffic in the VM, I start to get dropped packets in the rx_fifo queue in the hypervisor (there is only one VM per nic running) These "physical" nics hosting the VF nics are using the igb driver 0000:07:10.0 'I350 Ethernet Controller Virtual Function 1520' drv=vfio-pci unused=igbvf,igb_uio 0000:07:10.1 'I350 Ethernet Controller Virtual Function 1520' drv=vfio-pci unused=igbvf,igb_uio 0000:07:00.0 'I350 Gigabit Network Connection 1521' if=ens2f0 drv=igb unused=igb_uio,vfio-pci 0000:07:00.1 'I350 Gigabit Network Connection 1521' if=ens2f1 drv=igb unused=igb_uio,vfio-pci Is there a better driver I can use on the parent nic?, as it seems this is where the problems are arising. I cant bind the vfio-pci nic to the parent nic, but that seems obvious as the vfio-pci seem to be for VF nics only?? /Thanks
