Date: Mon, 25 Feb 2019 02:40:07 -0800 From: xiangxia.m.yue@...il.com To: saeedm@...lanox.com, gerlitz.or@...il.com Cc: netdev@...r.kernel.org, Tonghao Zhang <xiangxia.m.yue@...il.com> Subject: [PATCH net-next v2 5/5] net/mlx5e: Return -EOPNOTSUPP when attempting to offload an unsupported action From: Tonghao Zhang <xiangxia.m.yue@...il.com> The encapsulation is not supported for mlx5 VFs. When we try to offload that action, the -EINVAL is returned, but not -EOPNOTSUPP. This patch changes the returned value and ignore to confuse user. For example: (p2p1_0 is VF net device) tc filter add dev p2p1_0 protocol ip parent ffff: prio 1 flower skip_sw \ src_mac e4:11:22:33:44:01 \ action tunnel_key set \ src_ip 1.1.1.100 \ dst_ip 1.1.1.200 \ dst_port 4789 id 100 \ action mirred egress redirect dev vxlan0 "RTNETLINK answers: Invalid argument" Signed-off-by: Tonghao Zhang <xiangxia.m.yue@...il.com> --- drivers/net/ethernet/mellanox/mlx5/core/en_tc.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/net/ethernet/mellanox/mlx5/core/en_tc.c b/drivers/net/ethernet/mellanox/mlx5/core/en_tc.c index d9fcb14..f5029ea 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/en_tc.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/en_tc.c @@ -2302,7 +2302,8 @@ static int parse_tc_nic_actions(struct mlx5e_priv *priv, } break; default: - return -EINVAL; + NL_SET_ERR_MSG_MOD(extack, "The offload action is not supported"); + return -EOPNOTSUPP; } } @@ -2624,7 +2625,8 @@ static int parse_tc_fdb_actions(struct mlx5e_priv *priv, break; } default: - return -EINVAL; + NL_SET_ERR_MSG_MOD(extack, "The offload action is not supported"); + return -EOPNOTSUPP; } } -- 1.8.3.1
