Subject: [dpdk-dev] [PATCH v2 3/5] eventdev/rx_adapter:add per queue event buffer configure support
Date: Tue, 21 Sep 2021 04:45:57 -0500	[thread overview]
Message-ID: <20210921094559.1788022-3-s.v.naga.harish.k@intel.com> (raw)
In-Reply-To: <20210921094559.1788022-1-s.v.naga.harish.k@intel.com>

To configure per queue event buffer size, applications sets
``rte_event_eth_rx_adapter_params::use_queue_event_buf`` flag
as true and is passed to ``rte_event_eth_rx_adapter_create_with_params``
api.

The per queue event buffer size is populated  in
``rte_event_eth_rx_adapter_queue_conf::event_buf_size`` and passed
to ``rte_event_eth_rx_adapter_queue_add`` api.
