Subject: [PATCH v2] net: intel: ixgbe: use new api ethtool_{get|set}_link_ksettings

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.

As I don't have the hardware, I'd be very pleased if
someone may test this patch.

Signed-off-by: Philippe Reynes <tremyfr@...il.com>

Changelog:
v2:
- fix compilation (thanks andrewx bowers)
