From b168cff0b9b216e68215cdb28db999f542482a56 Mon Sep 17 00:00:00 2001 From: Eli Britstein Date: Wed, 19 Dec 2018 09:29:10 +0200 Subject: [PATCH] net/mlx5e: Fail attempt to offload e-switch TC encap flows with vlan on underlay Currently we don't support nor fail attempts to offload encap flows routed to vlan device on the underlay network. We wrongly consider a vlan underlay device to be on the same e-switch b/c the switchdev ID is retrieved recursively. Add explicit check for that and fail such attempts. Also align to a more strict check for the ingress and the underlay devices to practically be on the same eswitch. Fixes: ce99f6b97fcd ('net/mlx5e: Support SRIOV TC encapsulation offloads for IPv6 tunnels') Fixes: 3e621b19b0bb ('net/mlx5e: Support TC encapsulation offloads with upper devices') Signed-off-by: Eli Britstein Reviewed-by: Roi Dayan Signed-off-by: Saeed Mahameed --- drivers/net/ethernet/mellanox/mlx5/core/en/tc_tun.c | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/drivers/net/ethernet/mellanox/mlx5/core/en/tc_tun.c b/drivers/net/ethernet/mellanox/mlx5/core/en/tc_tun.c index c90a0f9cb6e1..0d24e9648c21 100644 --- a/drivers/net/ethernet/mellanox/mlx5/core/en/tc_tun.c +++ b/drivers/net/ethernet/mellanox/mlx5/core/en/tc_tun.c @@ -15,6 +15,10 @@ static int get_route_and_out_devs(struct mlx5e_priv *priv, struct net_device *uplink_dev, *uplink_upper; bool dst_is_lag_dev; + /* we currently don't offload vlan on underlay */ + if (is_vlan_dev(dev)) + return -EOPNOTSUPP; + uplink_dev = mlx5_eswitch_uplink_get_proto_dev(esw, REP_ETH); uplink_upper = netdev_master_upper_dev_get(uplink_dev); dst_is_lag_dev = (uplink_upper && @@ -28,6 +32,8 @@ static int get_route_and_out_devs(struct mlx5e_priv *priv, if (!switchdev_port_same_parent_id(priv->netdev, dev) || dst_is_lag_dev) *out_dev = uplink_dev; + else if (!mlx5e_eswitch_rep(dev)) + return -EOPNOTSUPP; else *out_dev = dev; -- 2.11.0
