+From: John Ronciak <john.ronciak@intel.com>
+Subject: ixgbe driver update to add Longcove (SFP+) NIC support for FCoE needs
+Acked-by: Karsten Keil <kkeil@novell.com>
+Reference: bnc#442411
+
+
+The patch that will be attached is to update the ixgbe driver to add SFP+ NIC
+support to SLES11 beta4 version of the ixgbe driver.  NIC have been sent to
+Nurnberg for testing purposes.  We have already been testing the patch with
+both our test lab and in our FCoE testing.
