[dpdk-dev] [PATCH 1/1] net/mlx5: fix memory leak when releasing a drop action

[Yunjian Wang]

When the memory for hrxq->action is allocated in mlx5_devx_hrxq_new().
But it was not being freed when the drop action was released in
mlx5_devx_drop_action_destroy(). These cause a memory leak.

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