#1592467 — [PATCH v2] net: smsc: smc91x: 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.

Ok, I tested it, with :
    ethtool -s eth0 duplex half autoneg off speed 10
    ethtool eth0
       => see the changes
    ping -f x.x.x.x
    ethtool -s eth0 duplex full autoneg on
    ethtool eth0
       => see the changes
    ping -f x.x.x.x

This both with your patch and without, it works in both cases, and the former as
a smaller throughput, which makes me believe the patch is fine.

Cheers.
