From 2ce718e809eb898344f679822ccb974cd977b8a6 Mon Sep 17 00:00:00 2001 From: Wei Dai Date: Mon, 21 Aug 2017 14:21:09 +0800 Subject: [PATCH] net/ixgbe: add VLAN info in queue info msg to VF This patch is to align with PF kernel driver version 5.1.3 to add the number of queues to transmit VLAN packets in msg of queue info to VF. If DCB is enabled, it is the number of DCB traffic classes. If DCB is not enabled and default VLAN is enabled, it is 1. For other cases, it is 0.
