Bryan Whitehead says:

====================
lan743x: Add features to lan743x driver

This patch series adds extra features to the lan743x driver.

Updates for v4:
Patch 6/8 - Modified get/set_wol to use super set of
	    MAC and PHY driver support.
Patch 7/9 - In set_eee, return the return value from phy_ethtool_set_eee.

Updates for v3:
Removed patch 9 from this series, regarding PTP support
Patch 6/8 - Add call to phy_ethtool_get_wol to lan743x_ethtool_get_wol
Patch 7/8 - Add call to phy_ethtool_set_eee on (!eee->eee_enabled)

Updates for v2:
Patch 3/9 - Used ARRAY_SIZE macro in lan743x_ethtool_get_ethtool_stats.
Patch 5/9 - Used MAX_EEPROM_SIZE in lan743x_ethtool_set_eeprom.
Patch 6/9 - Removed unnecessary read of PMT_CTL.
	    Used CRC algorithm from lib.
	    Removed PHY interrupt settings from lan743x_pm_suspend
	    Change "#if CONFIG_PM" to "#ifdef CONFIG_PM"
====================
