#
# Configure OVS to use DPDK
#
# === Parameters
#
# [*memory_channels*]
# (optional) The number of memory channels to use as an integer.
#
# [*driver_type*]
# (Optional) The DPDK Driver type
# Defaults to 'vfio-pci'
# This parameter is required only for OVS versions <= 2.5.
#
# [*host_core_list*]
# (optional) The list of cores to be used by the lcore threads.
# The host_core_list is a string with format as <c1>[-c2][,c3[-c4],...]
# where c1, c2, etc are core indexes between 0 and 128.
# For example, to configure 3 cores the value should be "0-2"
#
# [*package_ensure*]
# (Optional) State of the openvswitch package
# Defaults to 'present'.
#
# [*pmd_core_list*]
# (optional) The list of cores to be used by the DPDK PMD threads.
# The pmd_core_list is a string with format as <c1>[-c2][,c3[-c4],...] where
# c1, c2, etc are core indexes between 0 and 128
# For example, to configure 3 cores the value should be "0-2"
#
# [*socket_mem*]
# (Optional) Set the memory to be allocated on each socket
# The socket_mem is a string with comma separated memory list in MB in the
# order of socket numbers. For example, to allocate memory of 1GB for
# socket 1 and no allocation for socket 0, the value should be "0,1024"
# Defaults to undef.
#
# [*disable_emc*]
# (optional) Configure OVS to disable EMC.
#
# [*revalidator_cores*]
# (Optional) Number of cores to be used for OVS Revalidator threads.
#
# [*handler_cores*]
# (Optional) Number of cores to be used for OVS handler threads.
#
