When the hardware COS queue feature is enabled, in some cases the BIG-IP system sends an egress packet with a priority different from that of ingress packet on the same flow.
Egress packets are sent with an incorrect packet priority and delivered on the incorrect switch COS queues, resulting in lower performance.
Hardware COS queue feature is enabled.
Packet priority passthrough mode is now sending correct packet priority and delivering on the correct switch COS queue.
