Subject: [dpdk-dev] [PATCH v2 02/11] examples/l3fwd: split pipelines based on capability
Date: Wed, 4 Dec 2019 20:13:35 +0530
Message-ID: <20191204144345.5736-3-pbhagavatula@marvell.com> (raw)
In-Reply-To: <20191204144345.5736-1-pbhagavatula@marvell.com>

From: Sunil Kumar Kori <skori@marvell.com>

Add infra to split eventdev framework based on event Tx adapter
capability.
If event Tx adapter has internal port capability then we use
`rte_event_eth_tx_adapter_enqueue` to transmitting packets else
we use a SINGLE_LINK event queue to enqueue packets to a service
core which is responsible for transmitting packets.
