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
