Subject: [dpdk-dev] [PATCH] net/mlx5: fix indirect action modify rollback
Date: Wed, 21 Jul 2021 15:51:12 +0300 [thread overview]
Message-ID: <20210721125112.11161-1-dkozlyuk@nvidia.com> (raw)
mlx5_ind_table_obj_modify() first references queues from the new list,
then applies the new list to HW. In case of apply failure the function
dereferenced queues from the old list, while it should be the new list.
Fixes: fa7ad49e96b5 ("net/mlx5: fix shared RSS action update")
