For the stingray platform and other platforms needing tighter

Rename "def_cp_ring" to "async_cp_ring" to better reflect its
purpose (async event notifications) and to avoid confusion with
VNIC default receive completion rings.

5 years agonet/mlx5: fix Rx queue release of resources
Dekel Peled [Wed, 24 Jul 2019 09:05:11 +0000 (12:05 +0300)]
net/mlx5: fix Rx queue release of resources

Function rxq_release_rq_resources() releases resources of RQ object
created by DevX API.

This patch updates this function to properly clear the released
resources, to avoid repeated release of the same resource.

Fixes: dc9ceff73c99 ("net/mlx5: create advanced RxQ via DevX")
