From 9be9050134aaf09089f0cfb7723159eecc4a15e5 Mon Sep 17 00:00:00 2001 From: Wei Dai Date: Mon, 23 Oct 2017 14:43:57 +0800 Subject: [PATCH] net/ixgbe: fix PF DCB info When SRIOV is active, the function ixgbe_dev_get_dcb_info( ) should return the DCB traffic class info of its own queues, not including any DCB info of the queues of any its VF. When VMDQ is active, all queues are belonged to the PF, the function ixgbe_dev_get_dcb_info can return DCB info of all queues.
