From 1f4d51836f5e49f2e5201f1daf90239c04b3faf2 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Sat, 14 May 2011 01:16:02 +0000 Subject: [PATCH] ixgbe: fix ring assignment issues for SR-IOV and drop cases This change fixes the fact that we would trigger a null pointer dereference or specify the wrong ring if the rings were restored. This change makes certain that the DROP queue is a static value, and all other rings are based on the ring offsets for the PF.
