#1379339 — [PATCH 0/3] fec: ethtool: move to new api {get|set}_link_ksettings

Ethtool has a new api {get|set}_link_ksettings that deprecate
the old api {get|set}_settings. We update the fec driver to use
this new ethtool api.

For this first version, I've converted old u32 value in phy structure
to link_modes structure. Another way would be to replace u32 in
phy structure to use DECLARE_LINK_MODE_MASK for advertising, ....

#1379346 — [PATCH 2/3] phy: add generic function to support ksetting support

The old ethtool api (get_setting and set_setting) has
generic phy functions phy_ethtool_sset and phy_ethtool_gset.
To supprt the new ethtool api (get_link_ksettings and
set_link_ksettings), we add generic phy function
phy_ethtool_ksettings_get and phy_ethtool_ksettings_set.

It seems fine. There have many drivers need to update .set_settings/. get_settings, not only fsl fec driver.
And whether there still need to keep the old interface in phy.c driver ?

Andy
