[ovs-discuss] [OVN] Support for QoS on Floating IP

[Maciej Jozefczyk]

Hello,

Solution found and it is easy. It is just a matter of proper match.
Example row in QoS table:

_uuid               : 85f400e9-f82f-47f0-ac93-b151ed843734
action              : {}
bandwidth           : {burst=200, rate=200}
direction           : from-lport
external_ids        : {}
match               : "inport == \"96242e8f-602f-4077-984a-5659e84a8c4f\"
&& ip4.src == 172.24.5.126 &&
is_chassis_resident(\"cr-lrp-96242e8f-602f-4077-984a-5659e84a8c4f\")"
priority            : 20002

Where inport is a gateway Logical Port, and ipv4.src is Floating IP.

Thanks,
Maciej
