Subject: [dpdk-dev] [PATCH 1/2] ethdev: add flow action type update as an offload
Date: Fri, 25 Oct 2019 20:51:40 +0530
Message-ID: <20191025152142.12887-1-pbhagavatula@marvell.com> (raw)

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Add new Rx offload flag `DEV_RX_OFFLOAD_FLOW_MARK` that can be used to
enable/disable PMDs write to `rte_mbuf::hash::fdir::hi` and
`rte_mbuf::ol_flags` when flow actions `RTE_FLOW_ACTION_MARK` and
`RTE_FLOW_ACTION_FLAG` are enabled.

PMDs notify the validity of `rte_mbuf::hash:fdir::hi` to the applcation
by enabling `PKT_RX_FDIR_ID` flag in `rte_mbuf::ol_flags`.
