Currently, stmmac driver relies on the HW PMT to support WOL. We want to support phy based WOL.
patch1 is a small improvement to disable WAKE_MAGIC for PMT case if no pmt_magic_frame. patch2 and patch3 are two prepation patches. patch4 implement the phy based WOL patch5 tries to save a bit energy if WOL is enabled.
