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.

Jisheng Zhang (5):
  net: stmmac: Remove WAKE_MAGIC if HW shows no pmt_magic_frame
  net: stmmac: Move device_can_wakeup() check earlier in set_wol
  net: stmmac: only call pmt() during suspend/resume if HW enables PMT
  net: stmmac: Support WOL with phy
  net: stmmac: speed down the PHY, if WoL used, to save energy

Series applied to net-next, thanks.
