Subject[PATCH 5.4 026/104] net/mlx5: DR, Enable counter on non-fwd-dest objects
Date
From: Erez Shitrit <erezsh@mellanox.com>

commmit b850a82114df9b0ec1d191dc64eed1f20a772e0f upstream.

The current code handles only counters that attached to dest, we still
have the cases where we have counter on non-dest, like over drop etc.

Fixes: 6a48faeeca10 ("net/mlx5: Add direct rule fs_cmd implementation")
