Yes. It is implemented in HW. Congestion management is applied on ethdev Rx queue using rte_eth_cman_config() API. Once it is configured, it applies to all the packets that steer towards that particular ethdev Rx queue. This feature help to skip the congestion management processing based on the packet color identified by the rte_flow meter object. For example, If one Rx queue configured as RED congestion and application wants to bypass the RED congestion processing for all GREEN color packet can be expressed though this API proposal.
