Subject: [PATCH v6 1/3] eventdev/eth_rx: add params set/get APIs
Date: Fri, 10 Feb 2023 11:37:42 -0600 [thread overview]
Message-ID: <20230210173744.3597666-1-s.v.naga.harish.k@intel.com> (raw)
In-Reply-To: <20230210134646.3407253-1-s.v.naga.harish.k@intel.com>
The adapter runtime configuration parameters defined in the
struct rte_event_eth_rx_adapter_runtime_params can be configured
and retrieved using rte_event_eth_rx_adapter_runtime_params_set() and
rte_event_eth_tx_adapter_runtime_params_get() respectively.
