Implement ethtool_ops get_wol and set_wol. Implement Wake-on-LAN support. Wol requires hardware board support which use sub id to identify. Magic packets are checked by fw, for now just support WAKE_MAGIC. Signed-off-by: Mengyuan Lou <mengyuanlou@net-swift.com> Signed-off-by: David S. Miller <davem@davemloft.net>
