# neutron::plugins::ml2::type_driver used by neutron::plugins::ml2
#
# === Parameters:
#
# [*flat_networks*]
# (required) List of physical_network names with which flat networks can be created.
# Use * to allow flat networks with arbitrary physical_network names.
#
# [*tunnel_id_ranges*]
# (required) Comma-separated list of <tun_min>:<tun_max> tuples enumerating ranges
# of GRE tunnel IDs that are available for tenant network allocation
#
# [*network_vlan_ranges*]
# (required) List of <physical_network>:<vlan_min>:<vlan_max> or <physical_network>
# specifying physical_network names usable for VLAN provider and tenant networks, as
# well as ranges of VLAN tags on each available for allocation to tenant networks.
#
# [*vni_ranges*]
# (required) Comma-separated list of <vni_min> tuples enumerating ranges of VXLAN VNI IDs
# that are available for tenant network allocation.
#
# [*vxlan_group*]
# (required) Multicast group for VXLAN. If unset, disables VXLAN multicast mode.
#
# [*max_header_size*]
# (optional) Geneve encapsulation header size is dynamic, this value is used to calculate
# the maximum MTU for the driver.
