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
