Subject: [ethtool PATCH 1/4] ethtool: remove strings based approach for
	displaying n-tuple

This change is meant to remove the strings based approach for displaying
n-tuple filters.  A follow-on patch will replace that functionality with a
network flow classification based approach that will get the number of
filters, get their locations, and then request and display them
individually.
