From 8efcf6bb48e52c7ee679e7f441d52dfc5dd3dc16 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Thu, 11 Oct 2018 07:48:06 +0000 Subject: [PATCH] mlxsw: reg: Add Tunneling NVE QoS Default Register The TNQDR register configures the default QoS settings for NVE encapsulation. It will be used to set the default DSCP of each port to 0, so that when DSCP is set to inherit and the overlay packet does not have an IP header the outer DSCP will be set to 0, in accordance with the software data path.
