# vswitch: open-vswitch
# == Class: vswitch::ovs
#
# installs openvswitch
#
# === Parameters:
#
# [*package_name*]
# (required) Name of OVS package.
#
# [*service_name*]
# (required) Name of OVS service.
#
# [*package_ensure*]
# (Optional) State of the openvswitch package
# Defaults to 'present'.
#
# [*enable_hw_offload*]
# (optional) Configure OVS to use
# Hardware Offload. This feature is
# supported from ovs 2.8.0.
# Defaults to false.
#
# [*disable_emc*]
# (optional) Configure OVS to disable EMC.
# Defaults to false.
#
# [*vlan_limit*]
# (optional) Number of vlan layers allowed.
# Default to undef
#
# [*vs_config*]
# (optional) allow configuration of arbitrary vswitch configurations.
# The value is an hash of vs_config resources. Example:
# { 'other_config:foo' => { value => 'baa' } }
# NOTE: that the configuration MUST NOT be already handled by this module
# or Puppet catalog compilation will fail with duplicate resources.
#
# [*skip_restart*]
# (optional) Skip restarting the service even when updating some options
# which require service restart. Setting this parameter to true avoids
# immedicate network distuption caused by restarting the ovs daemon.
# Defaults to false.
