Subject: [PATCH v4 net-next] net: mvneta: implement .set_wol and .get_wol

From: Jingju Hou <houjingj@...vell.com>

From: Jingju Hou <houjingj@...vell.com>

The mvneta itself does not support WOL, but the PHY might.
So pass the calls to the PHY

since v3:
 - really fix the build error

since v2,v1:
 - using phy_dev member in struct net_device
 - add commit msg
