One thing I noticed is alx_select_powersaving_speed() will return 0
when there is no link but leaves *speed uninitialized.
Then __alx_shutdown() prints e.g.
   alx 0000:03:00.0 eth0: wol: ctrl=3, speed=FFFF8801
In this case the
  alx_write_phy_reg(hw, ALX_MII_IER, 0);
is skipped in alx_select_powersaving_speed().
However, it should still be done in alx_pre_suspend()
when WOL is disabled.  But it might be we need to move
the alx_clear_phy_intr() in __alx_shutdown() down.

I'm also not sure why alx_get_phy_link() reads MII_BMSR
twice, but the old driver from compat-wireless-3.6.8-1-snpc
also does it, it seems deliberate.

Unless someone beats me to it I will try to debug
on the weekend.

BTW, it is WoLAN not WoWLAN :-)

Thanks,
Johannes
