Subject: [net 09/13] net/mlx5: Don't maintain a case of del_sw_func being null
Date: Fri, 22 May 2020 17:40:45 -0700 [thread overview]
Message-ID: <20200523004049.34832-10-saeedm@mellanox.com> (raw)
In-Reply-To: <20200523004049.34832-1-saeedm@mellanox.com>
From: Roi Dayan <roid@mellanox.com>
Add del_sw_func cb for root ns. Now there is no need to
maintain a case of del_sw_func being null when freeing the node.
Fixes: 2cc43b494a6c ("net/mlx5_core: Managing root flow table")
