[PATCH net-next 1/3] net: sb1250-mac: Add ethtool link settings support

[Florian Fainelli <f.fainelli@gmail.com>]

The driver connects to its PHY through phylib, but does not provide
ethtool operations. As a result, ethtool cannot report or configure the
link settings.

Use the phylib get_link_ksettings and set_link_ksettings helpers, and
provide ethtool_op_get_link for carrier reporting. The helpers return
-ENODEV when the PHY is not attached, as the driver attaches it when
the interface is opened and disconnects it when the interface is closed.
