# == Class: ovsdpdk
#
# Configures and installs OVS with DPDK support service
#
# == Parameters:
#
# [*rte_target*]
# rte_target to compile OVS DPDK
# Defaults to 'x86_64-native-linuxapp-gcc'
#
# [*ovs_dpdk_mem_segments*]
# another parameter for OVS DPDK build
# Defaults to '256'
#
# [*ovs_dpdk_rte_librte_vhost*]
# another parameter for OVS DPDK build
# Defaults to 'y'
#
# [*ovs_dpdk_vhost_user_debug*]
# (True/False) indicates whether to enable debugging for VHOST USER in DPDK
# Defaults to 'n'
#
# [*ovs_allocate_hugepages*]
# (True/False) indicates whether to allocate hugepages during ovs-dpdk startup
# Defaults to 'True'
#
# [*ovs_datapath_type*]
# OVS bridges will be set to use this datapath, possible values are 'system'
# for kernel OVS and 'netdev' for userspace OVS
# Defaults to 'netdev'
#
# [*ovs_tunnel_cidr_mapping*]
# (bridge:cidr) when specified, this option enables automatic assignment of
# the tunnel endpoint ip to a specific interface.
# e.g. OVS_TUNNEL_CIDR_MAPPING=br-phy:192.168.50.1/24 assignes the ip of
# 192.168.50.1 with subnetmask 255.255.255.0 to the br-phy local port.
# This is required to enabled vxlan or other tunneling protocols with ovs-dpdk
# and dpdk physical ports.
#
# [*ovs_hugepage_mount*]
# mount point to use for hugepages. It's created and hugepages mounted if
# it doesn't exist on the filesystem
# Defaults to '/mnt/huge'
#
# [*ovs_hugepage_mount_pagesize*]
# preffered hugepage size (2M/1G)
# Defaults to OS defaults if not set. If '1G' value is used hugepages should be
# allocated before starting ovs (e.g. kernel boot command line)
#
# [*ovs_num_hugepages*]
# amount of hugepages to mount if ovs_allocate_hugepages is True
#
# [*ovs_socket_mem*]
# amount of memory to allocate on socket, recommended minimum is '512' MB
#
# [*ovs_mem_channels*]
# number of memory channels into the processor OVS will use
#
# [*ovs_core_mask*]
# cpu core mask in hexa format, is used for ovs-vswitchd process as -c option
# Defaults is '2'
# Example:
# ovs_core_mask=3 (0x11 binary -> first two cores taken)
#
# [*ovs_pmd_core_mask*]
# mask in hexa format for PMD threads od OVS set in the db.
# ovs_pmd_core_mask value is used for other_config:pmd-cpu-mask parameter in
# ovsdb.
# Defaults is '4'. In case of HT enabled, it's 4 + sibling
#
# [*ovs_bridge_mappings*]
# (network:bridge) list of comma separated pairs of "physical network:bridge"
# used by OVS/DPDK.
# Example: ovs_bridge_mappings=default:br-eth1,defaul1:br-enp9s0f0
#
# [*ovs_dpdk_port_mappings*]
# (nic:bridge) list of comma separated pairs of "nic:bridge name" used by
# OVS/DPDK. "nic" must be a NIC interface present in the system
# "bridge" is the linux bridge created by OVS
# Example: ovs_dpdk_port_mappings=eth1:br-01,eth2:br02
#
# [*ovs_log_dir*]
# directory where ovs-vswitchd.log will be created
# Defaults: "/tmp"
#
# [*ovs_lock_dir*]
# directory containing OVS lock file
#
# [*ovs_interface_driver*]
# (vfio-pci/igb_uio) NIC driver to use for physical network interfaces.
# Drivers names are the ones supported by DPDK, i.e: not the kernel names.
# Defaults: "igb_uio"
#
# [*ovs_patches*]
# *todo*
#
# [*ovs_dpdk_patches*]
# *todo*
#
