From 800bd607c31e648267e8a1055b14ad27bde943f5 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Sat, 2 Jun 2012 00:11:02 +0000 Subject: ixgbe: Add function for obtaining FCoE TC based on FCoE user priority In upcoming patches it will become increasingly common to need to determine the FCoE traffic class in order to determine the correct queues for FCoE. In order to make this easier I am adding a function for obtaining the FCoE traffic class based on the user priority.
