Hello,

I have couple of questions regarding QoS support in OVN -

i) Why was the QoS approach of ingress policing replaced with egress shaping in 
OVN as part of this commit ? -
https://github.com/openvswitch/ovs/commit/a6095f815ed9b8a8d4e9989179d14308c1ed112c

Since egress shaping would require creation and management of multiple queues, 
hence I believe that it is more resource intensive.
Are there any known performance issues/considerations that have come up since 
the switch to egress shaping ?

ii) Why can't both policing and shaping be made configurable through OVN, 
instead of replacing one for other ?
For OVN users who want to achieve basic rate-limiting, being able to configure 
policing looks like a good option.

Thanks,
Anuj Gupta
