net: ethtool: allow MAC drivers to override ethtool get_ts_info
Check whether the MAC driver has implemented the get_ts_info() method first, and call it if present. If this method returns -EOPNOTSUPP, defer to the phylib or default implementation. XXX: review any drivers that use phylib and provide get_ts_info(). Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk>
