## Change UIO driver used by VPP, Options are: uio_pci_generic, vfio-pci

# uio-driver uio_pci_generic
## Disable mutli-segment buffers, improves performance but
## disables Jumbo MTU support
# no-multi-seg
## Increase number of buffers allocated, needed only in scenarios with
## large number of interfaces and worker threads. Value is per CPU socket.
## Default is 32768

## Change hugepages allocation per-socket, needed only if there is need for
## larger number of mbufs. Default is 256M on each detected CPU socket
