Neutron to affect scheduling).
* Bandwidth guarantees for ports can only be requested on networks

* In Stein there is no support for networks with multiple physnets.
However some simpler multi-segment networks are still supported:

by a ``direct-physical`` port.
Since 2023.1 (Antelope), Open vSwitch and OVN mechanism drivers can specify
the available bandwidth for tunnelled networks (SR-IOV does not support these
network types yet). The key "rp_tunnelled" is used to model those networks
that are not backed by a physical network. This bandwidth models the limits
of the VTEP/TEP interface used to send the tunnelled traffic (VXLAN, Geneve).

"rp_tunnelled" is not a bridge nor an interface present in the host.
The ML2/OVS agent will read the host local "resource_provider_bandwidths"
and will assign, by default, the "rp_tunnelled" resource provider to
the local host where is running. In other words, it is not needed to
populate "resource_provider_hypervisors" with the host assigned to this
specific resource provider.

ML2/OVS and ML2/OVN now support modelling tunnelled networks in the
Placement API. The "tunnelled_network_rp_name" configuration option
defines the resource provider name used to represent all tunnelled
networks in a compute node (by default "rp_tunnelled"). If this string
is present in the "resource_provider_bandwidths" dictionary, the
corresponding mechanism driver will create a resource provider for
the overlay traffic.
