Subject: net/mlx5: fix Rx queue release of resources
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fa071809c6dfcc446ac992db41f6f9e0a03259bb;p=dpdk.git

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")
