From: Philippe Reynes Date: Sat, 4 Feb 2017 21:05:06 +0000 (+0100) Subject: i40e: use new api ethtool_{get|set}_link_ksettings X-Git-Tag: MMI-PSA29.97-13-9~5649^3~414^2~12 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a7f909405bf9bd3a737a39d3a433a4eae4d7eb21;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git i40e: 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.
