We discussed this RFE during the drivers meeting (see [1]) and agreed that this is a good idea, but we would like you to add some extra details and the exact goals to have clear direction and see if it is possible with OVN.

I have test it that l3 acl with ovn backend.It is work fine when put any stateless acls for lrp which is gateway of subnet.
So we could implement one driver with ovn backend through transform firewall rules to stateless acls for lrp.
Any one has other opinions?

Is it only effective in the gateway subnet? What about the internal subnet interface?
