From cdf485be3a63d1f34293740fb726088c6840ceea Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Sat, 11 Feb 2012 06:26:00 +0000 Subject: [PATCH] ixgbe: dcb: use DCB config values for FCoE traffic class on open Disabling and enabling DCB can cause FCoE hardware initialization to occur on the incorrect traffic class when the up2tc mapping has not yet been reconfigured. Fix this by using the DCB configuration maps that are correct and will be pushed at mqprio after DCB driver setup completes successfully.
