From fd786b7b4731b7aa9796cfd251238ffaab71d725 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Sat, 12 Jan 2013 06:33:31 +0000 Subject: [PATCH] ixgbe: Add function for setting XPS queue mapping This change adds support for ixgbe to configure the XPS queue mapping on load. The result of this change is that on open we will now be resetting the number of Tx queues, and then setting the default configuration for XPS based on if ATR is enabled or disabled.
