This resolves the issue of garbage values output when querying with self test via ethtool. before: $ ethtool -t eth2 The test result is PASS The test extra info: Link Test 0 Speed Test 1768697188 Health Test 758528120 Loopback Test 3288687 after: $ ethtool -t eth2 The test result is PASS The test extra info: Link Test 0 Speed Test 0 Health Test 0 Loopback Test 0 Fixes: 7990b1b5e8bd ("net/mlx5e: loopback test is not supported in switchdev mode") Signed-off-by: Lama Kayal Reviewed-by: Gal Pressman Signed-off-by: Saeed Mahameed --- drivers/net/ethernet/mellanox/mlx5/core/en_selftest.c | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/net/ethernet/mellanox/mlx5/core/en_selftest.c b/drivers/net/ethernet/mellanox/mlx5/core/en_selftest.c index 8c9163d2c646..08a75654f5f1 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/en_selftest.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/en_selftest.c @@ -334,6 +334,7 @@ void mlx5e_self_test(struct net_device *ndev, struct ethtool_test *etest, netdev_info(ndev, "\t[%d] %s start..\n", i, st.name); buf[count] = st.st_func(priv); netdev_info(ndev, "\t[%d] %s end: result(%lld)\n", i, st.name, buf[count]); + count++; } mutex_unlock(&priv->state_lock); -- 2.11.0
