From 316793fb2d907d4726b4977b6be26ec653827774 Mon Sep 17 00:00:00 2001 From: Eli Britstein Date: Mon, 29 Apr 2019 18:14:01 +0000 Subject: [PATCH] net/mlx5: E-Switch: Introduce prio tag mode Current ConnectX HW is unable to perform VLAN pop in TX path and VLAN push on RX path. To workaround that limitation untagged packets will be tagged with VLAN ID 0x000 (priority tag) and pop/push actions will be replaced by VLAN re-write actions (which are supported by the HW). Introduce prio tag mode as a pre-step to controlling the workaround behavior.
