OvsDpdkCoreList:
description: >
List of cores to be used for DPDK lcore threads. Note, these threads
are used by the OVS control path for validator and handling functions.

OvsDpdkSocketMemory:
default: ""
description: >
Sets the amount of hugepage memory to assign per NUMA node. It is
recommended to use the socket closest to the PCIe slot used for the
desired DPDK NIC. The format should be in "<socket 0 mem>, <socket 1
mem>, <socket n mem>", where the value is specified in MB. For example:
"1024,0".
type: string
OvsDpdkDriverType:
default: "vfio-pci"
description: >
DPDK Driver type. Ensure the Overcloud NIC to be used for DPDK supports
this UIO/PMD driver.
type: string
OvsPmdCoreList:
description: >
A list or range of CPU cores for PMD threads to be pinned to. Note, NIC
location to cores on socket, number of hyper-threaded logical cores, and
desired number of PMD threads can all play a role in configuring this
setting. These cores should be on the same socket where
OvsDpdkSocketMemory is assigned. If using hyperthreading then specify
both logical cores that would equal the physical core. Also, specifying
more than one core will trigger multiple PMD threads to be spawned which
may improve dataplane performance.
