#1595566 — [PATCH] net: hyperv: 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.

No change in behavior. Same as before driver always reports duplex UNKNOWN and speed change
is not useful.
