[dpdk-dev] [PATCH v2 2/2] net/mlx5: fix resource leak when releasing a drop action

[Yunjian Wang]

Currently, the resources for hrxq->action are allocated in
mlx5_devx_hrxq_new(). But it was not being freed when the
drop action was released in mlx5_devx_drop_action_destroy().
So, fix is to free the resources in mlx5_devx_tir_destroy().

Fixes: bc5bee028ebc ("net/mlx5: create drop queue using DevX")
