Subject: [ethtool 3/3] ethtool: add ixgbevf support for register dump
From: Jacob Keller <jacob.e.keller@...el.com>
This patch adds support for the ixgbevf driver, which previously was printing
out as hex dump, and in the driver via printk. This patch corrects the
implementation to have a new ixgbevf_reg_dump function that will format the
register output in a more human readable format.
