Shannon Nelson 9ac7726637 i40e: add switch for link polling
There's been some need for controlling the periodic link polling for
debugging link issues.  This patch enables switching it off and on
through an ethtool private flag.  The link poll remains on by default,
but can be turned off with
	ethtool --set-priv-flags p261p1 LinkPolling off
and later turned back on with
	ethtool --set-priv-flags p261p1 LinkPolling on

To check the current status, use
	ethtool --show-priv-flags p261p1
