Subject: [net-2.6 PATCH] ixgbe: fix possible NULL pointer deference in shutdown path
Date: Wed, 01 Dec 2010 22:54:53 -0800 [thread overview]
Message-ID: <20101202065447.13252.88901.stgit@localhost.localdomain> (raw)
From: Don Skidmore <donald.c.skidmore@intel.com>
After freeing the rings we were not zeroing out the ring count values.
This patch now clears these counts correctly.
