Subject: [dpdk-dev] [PATCH 3/3] ethdev: improve flow mark Rx offload deprecation notice
Date: Tue, 19 Nov 2019 12:05:44 +0000
Message-ID: <1574165145-23960-3-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1574165145-23960-1-git-send-email-arybchenko@solarflare.com>

The deprecation notice is required since it adds more requirements
when RTE flow mark and flag actions may be used and require
changes in applications.

-* ethdev: New offload flags ``DEV_RX_OFFLOAD_FLOW_MARK`` will be added in 19.11.
-  This will allow application to enable or disable PMDs from updating
-  ``rte_mbuf::hash::fdir``.
-  This scheme will allow PMDs to avoid writes to ``rte_mbuf`` fields on Rx and
-  thereby improve Rx performance if application wishes do so.
-  In 19.11 PMDs will still update the field even when the offloads are not
-  enabled.
+* ethdev: New offload flag ``DEV_RX_OFFLOAD_FLOW_MARK`` will be added in 20.02.
+  This will provide application an information if ``RTE_FLOW_ACTION_TYPE_MARK``
+  or ``RTE_FLOW_ACTION_TYPE_FLAG`` is supported and, what is more important,
+  allow an application to let PMD know that it would like to use these
+  features.
+  PMD may use the information to choose optimal datapath implementation and
+  configure HW appropriately to optimize performance and/or resources usage.
 
 * cryptodev: support for using IV with all sizes is added, J0 still can
   be used but only when IV length in following structs ``rte_crypto_auth_xform``,
