Subject: [PATCH v8 net-next 06/12] net: fec: convert to ndo_hwtstamp_get() and ndo_hwtstamp_set()
The hardware timestamping through ndo_eth_ioctl() is going away.
Convert the FEC driver to the new API before that can be removed.
After removing the timestamping logic from fec_enet_ioctl(), the rest
is equivalent to phy_do_ioctl_running().
