Subject: [dpdk-dev] [PATCH v13 1/2] ethdev: add an API to get device configuration
Date: Thu, 14 Oct 2021 18:31:23 +0800	[thread overview]
Message-ID: <20211014103124.528877-2-jie1x.wang@intel.com> (raw)
In-Reply-To: <20211014103124.528877-1-jie1x.wang@intel.com>

The driver may change offloads info into dev->data->dev_conf
in dev_configure which may cause apps use outdated values.

Add a new API to get actual device configuration.
