Subject: [PATCH] ethdev: add API to get device configuration
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in dev_configure which may cause apps use outdated values.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.
Signed-off-by: Jie Wang <jie1x.wang@intel.com>
Acked-by: Andrew Rybchenko <andrew.rybchenko@oktetlabs.ru>
Reviewed-by: Ferruh Yigit <ferruh.yigit@intel.com>
Conflict: mv ethdev dir to librte_ethdev; move version.map to rte_ethdev_version.map; remove the modify of release_21_11.rst
