Confirmed. If I use the "-b" option in ether-wake WoL works for my
system with plain 3.1 kernel, i.e. without the patch.

As "-b" is not the default for ether-wake it will come as a surprise
for the user that WoL is no longer working. Maybe we should reword the
patch subject to:

  r8169: driver shutdown unicast WoL regression
