Do you have any suggestions? Thanks! > Hi,
while I can't comment on the NIC-specific issues, I would just comment that it's really not recommended to use uio_pci_generic - or any other uio driver - for DPDK any more. You should consider switching to using vfio-pci. Even if there is no iommu enabled, vfio-pci still tends to give a better user experience. If iommu is enabled, you also get a lot more security from the memory protection it provides. Regards, /Bruce
