Linux 3.1 下使用 N-1030 的 WoWLAN

Question

Linux 3.1 增加了对 WoWLAN 的支持，据我所知，我的 Intel Centrino N-1030 卡支持 WoWLAN。但是，eth0 的 ethtool 给出的信息为：

# ethtool eth0
Settings for eth0:
    Supported ports: [ TP MII ]
    Supported link modes:   10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
                            1000baseT/Half 1000baseT/Full 
    Supported pause frame use: No
    Supports auto-negotiation: Yes
    Advertised link modes:  10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
                            1000baseT/Half 1000baseT/Full 
    Advertised pause frame use: Symmetric Receive-only
    Advertised auto-negotiation: Yes
    Speed: 10Mb/s
    Duplex: Half
    Port: MII
    PHYAD: 1
    Transceiver: internal
    Auto-negotiation: on
    Supports Wake-on: pg
    Wake-on: g
    Current message level: 0x000020c6 (8390)
                   probe link rx_err tx_err hw
    Link detected: no

和：

# ethtool wlan0
Settings for wlan0:
    Link detected: yes

因此，我的问题是，如何检查卡上是否启用了 WoWLAN，以及如何向无线接口发送魔术包。我谷歌搜索https://www.google.com/search?hl=en&q=WoWLAN+linux+3.1+how+to+还有一些其他类似的字符串，但我没有看到实际的命令...提前致谢。Oz
