What are you currently unable to do

Currently it's not possible to limit the ingress or egress bandwidth of a nic device which is using a ovn network, similar t how it would work on a bridge driver with limits.ingress.

What do you think would need to be added

I think this might be possible to do via OVNs QoS mechanism.

Preliminary tests via ovn-nbctl allowed me to restrict the bandwidth limits of a logical switch port.

By adjusting the ovn_driver and other components such as ovn_nb_actions, the QoS functionality could be implemented.

Since adding ACLs and QoS work slightly similar in OVN, we might should be able to use the ACL implementation as an example.
