Subject: [net-next 14/14] i40e: Save more link abilities when using ethtool

From: Henry Tieman <henry.w.tieman@...el.com>

Ethtool support needs to save more PHY information. The
added information includes FEC capabilities and 25G link
types. Without this change it is possible to lose 25G or
FEC settings by using ethtool.
