Subject: [ethtool PATCH 1/4] Add support for ESP as a separate protocol from AH

This change is meant to split out ESP from AH.  Currently they are present
as both a combined value, and two separate values.  In order to try and
support eventually splitting the two out into separate values this change
makes it so that ESP can be called out separately in ethtool.
