From 1315971fea66d2c1b09cab115a487898ba628cac Mon Sep 17 00:00:00 2001 From: Parav Pandit Date: Fri, 10 Jul 2020 21:12:44 +0300 Subject: [PATCH] net/mlx5e: Fix missing switch_id for representors Cited commit in fixes tag missed to set the switch id of the PF and VF ports. Due to this flow cannot be offloaded, a simple command like below fails to offload with below error. tc filter add dev ens2f0np0 parent ffff: prio 1 flower \ dst_mac 00:00:00:00:00:00/00:00:00:00:00:00 skip_sw \ action mirred egress redirect dev ens2f0np0pf0vf0 Error: mlx5_core: devices are not on same switch HW, can't offload forwarding. Hence, fix it by setting switch id for each PF and VF representors port as before the cited commit.
