Do not clear Broadcast/Multicast/Unicast Wake Flag or LanWake in Config5. This is necessary to preserve WOL state when the driver is loaded. The r8168 vendor driver used to write to both Config1 and Config5, but in recent versions, this is commented out. Here we keep writing PMEnable to Config1 because there may be older chips where PMEnable is not sticky.
