# == Class: neutron::agents::ml2::sriov
#
# Setups SR-IOV neutron agent when using ML2 plugin
#
# === Parameters
#
# [*package_ensure*]
# (optional) The state of the package
# Defaults to 'present'
#
# [*enabled*]
# (required) Whether or not to enable the OVS Agent
# Defaults to true
#
# [*manage_service*]
# (optional) Whether to start/stop the service
# Defaults to true
#
# [*physical_device_mappings*]
# (optional) Array of <physical_network>:<physical device>
# All physical networks listed in network_vlan_ranges
# on the server should have mappings to appropriate
# interfaces on each agent.
# Value should be of type array, Defaults to $::os_service_default
#
# [*polling_interval*]
# (optional) The number of seconds the agent will wait between
# polling for local device changes.
# Defaults to '2"
#
# [*exclude_devices*]
# (optional) Array of <network_device>:<excluded_devices> mapping
# network_device to the agent's node-specific list of virtual functions
# that should not be used for virtual networking. excluded_devices is a
# semicolon separated list of virtual functions to exclude from network_device.
# The network_device in the mapping should appear in the physical_device_mappings list.
# Value should be of type array, Defaults to $::os_service_default
#
# [*extensions*]
# (optional) Extensions list to use
# Defaults to $::os_service_default
#
# [*purge_config*]
# (optional) Whether to set only the specified config options
# in the sriov config.
# Defaults to false.
#
# [*number_of_vfs*]
# (optional) List of <physical_network>:<number_of_vfs> specifying the number
# VFs to be exposed per physical interface.
# For example, to configure two inteface with number of VFs, specify
# it as "eth1:4,eth2:10"
# Defaults to $::os_service_default.
#
# [*resource_provider_bandwidths*]
# (optional) List of <network_device>:<egress_bw>:<ingress_bw>
# Defaults to empty list
#
# [*resource_provider_hypervisors*]
# (optional) List of <bridge>:<hypervisor>
# Defaults to empty list
