Subject: [PATCH v10 1/3] ethdev: skip congestion management configuration
Date: Wed, 15 Feb 2023 23:12:49 +0530	[thread overview]
Message-ID: <20230215174251.1698253-1-rkudurumalla@marvell.com> (raw)
In-Reply-To: <20230215062532.1169860-1-rkudurumalla@marvell.com>

Introduce new flow action to skip congestion management configuration
This feature helps to skip the congestion management processing
based on per flow or the packet color identified by
rte_flow meter object. For example, If one Rx queue configured as
RED congestion and application wants tobypass the RED congestion
processing for all GREEN color packet can be expressed though
RTE_FLOW_ACTION_TYPE_SKIP_CMAN flow action
