E 文不好，大哭，请教一下大家？

偶不太明白ProtocolReceive中各个参数的意思，找到资料：
 * IN MacReceiveContext       - Specifies a context handle that the underlying NIC driver associates with the packet received from the network.
 * IN HeaderBuffer            - Points to the base virtual address of a range containing the buffered packet header.
 * IN HeaderBufferSize        - Specifies the number of bytes in the packet header.
 * IN LookAheadBuffer         - Points to the base virtual address of a range that contains LookaheadBufferSize bytes of buffered network packet data.
 * IN LookAheadBufferSize     - Specifies the number of bytes of network packet data in the lookahead buffer.
 * IN PacketSize              - Specifies the size, in bytes, of the network packet data. The length of the packet does not include the length of the header.

不过偶e文差劲，不是太明白，想请教一下大家？？？ :P

IN MacReceiveContext - Specifies a context handle that the underlying NIC driver associates with the packet received from the network.

* IN HeaderBuffer - Points to the base virtual address of a range containing the buffered packet header.
指向一系列包含缓冲的包头基本虚地址（MAC祯头部）
* IN HeaderBufferSize - Specifies the number of bytes in the packet header.
确定包头的字节数（MAC祯头部大小，14）
* IN LookAheadBuffer - Points to the base virtual address of a range that contains LookaheadBufferSize bytes of buffered network packet data.
指向一系列包含着在“开始缓冲中的网络包数据的字节数”字节的缓冲的网络包数据的基本虚地址（IP包的开始部分）
* IN LookAheadBufferSize - Specifies the number of bytes of network packet data in the lookahead buffer.
确定在开始缓冲中的网络包数据的字节数
* IN PacketSize - Specifies the size, in bytes, of the network packet data. The length of the packet does not include the length of the header
以字节的形式确定网络包数据的大小，包的长度不包括头的长度。
