ethtool工具中的wol功能一直很迷惑。今天看了代码将其帮助中下面的参数说明下，如果有不懂wake on lan的请自己到
intel官网查下。
p|u|m|b|a|g|s|d
if (wolopts & WAKE_PHY)//物理接口
*p++ = 'p';
if (wolopts & WAKE_UCAST)//单播
*p++ = 'u';
if (wolopts & WAKE_MCAST)//多播
*p++ = 'm';
if (wolopts & WAKE_BCAST)//广播
*p++ = 'b';
if (wolopts & WAKE_ARP)//arp包
*p++ = 'a';
if (wolopts & WAKE_MAGIC)//magic 包
*p++ = 'g';
if (wolopts & WAKE_MAGICSECURE)//magic 加密包
*p++ = 's';
d很明显了是关闭。
ethtool.c: if (adapter->wol & E1000_WUFC_EX)
ethtool.c: wol->wolopts |= WAKE_UCAST; u
ethtool.c: if (adapter->wol & E1000_WUFC_MC)

ethtool.c: adapter->wol = 0;
