From 897d7846b483da58d0b46bf806cf362a71501c56 Mon Sep 17 00:00:00 2001 From: Amir Vadai Date: Wed, 4 Apr 2012 21:33:27 +0000 Subject: [PATCH] net/mlx4_en: sk_prio <=> UP for untagged traffic Since vlan egress map is only good for tagged traffic, need to have other mapping to be used by untagged traffic. For that, the driver uses sch_mqprio mapping. This mapping could be set by using tc tool from iproute2 package. Mapped UP will be used by the HW for QoS purposes, but won't go out on the wire.
