在passthru里面获取ip地址的问题

各位大虾：
在网上查找过，可以通过PtRequestComplete里再
case NdisRequestSetInformation:
        ASSERT( Oid != OID_PNP_SET_POWER);
      if (Oid == OID_GEN_NETWORK_LAYER_ADDRESSES ）
  {    
             获取ip地址；
    }
有一个疑问，何时会进入到这个逻辑，我自己写了一个查询，试图进入上面的逻辑，但是不行

查询后，返回值始终是invalid oid，不知道什么原因，麻烦高人帮忙解答

协议驱动会调用的，你不必调用。一般初始化好久自动被协议驱动调用了。
