OVN applies logical switch QoS settings to egress interfaces. It
currently works by analyzing each br-int interface to see what the remote-ip
is on it, and then adding qdiscs to the tunnel-egress-iface associated
with this br-int interface.
This doesn't work as well when working with VLAN networks. In VLAN
networks, the interface on br-int associated with the localnet port on
the logical switch will be a patch port. It's connected to another
bridge, making it difficult to determine which interface (or interfaces) is
the egress interface on that connected bridge.
This series aims to mend this. On the bridge that is patched to br-int,
interfaces can have the boolean external-ids:ovn-egress-iface set to
true if this is an egress interface. This way, QoS can be applied to
these interfaces the same as is applied to tunnel interfaces.
Moreover rework qos code in order to add the capability to select automatically
the queue_id used to identify the device queue
Finally add the set_queue action to logical flows in Egress Port Security - L2 stage
for localnet QoS capable ports in order to set the physical_interface qdisc id
Changes since RFC:
- introduce build_lswitch_port_sec as a container for {in/out}_port_sec logical
flow configuration
- move ovn-egress-iface lookup in consider_localnet_port in order to avoid an
unnecessary port_binding lookup
Lorenzo Bianconi (3):
Add egress QoS mapping for non-tunnel interfaces
northd: add the possibility to define localnet as qos capable port
northd: interoduce logical flow for localnet egress shaping
