Subject: [net-2.6 PATCH 3/3] ixgbe: Display EEPROM version in ethtool -i queries

From: Jeff Kirsher <[email-masked]>
Date: Wed, 04 Feb 2009 17:39:43 -0800

From: PJ Waskiewicz <[email-masked]>

Currently ixgbe does not display the EEPROM version in ethtool -i, where
other drivers do.  The EEPROM version is located at offset 0x29.  This
patch adds support to display it.
