OOB信息写在哪儿哪？

麻烦您回答一下，谢谢了！

oob信息是和Packet结构相对应的
不需要自己分配
用NDIS_SET_PACKET_XXXXX的宏来访问
取出是用NDIS_GET_PACKET_XXXXX

OOB信息是一个结构体，Packet也是一个结构体，它们之间如何对应呢？各层驱动传输包描述符时OOB信息又是如何传输的呢？谢谢！

 建议你看一看 ndis.h就都明白了,呵呵.typedef struct _NDIS_PACKET
{
NDIS_PACKET_PRIVATE Private;

union
{
struct // For Connection-less miniports
{
UCHAR MiniportReserved[2*sizeof(PVOID)];
UCHAR WrapperReserved[2*sizeof(PVOID)];
};

struct
{
//
// For de-serialized miniports. And by implication conn-oriented miniports.
// This is for the send-path only. Packets indicated will use WrapperReserved
// instead of WrapperReservedEx
//
UCHAR MiniportReservedEx[3*sizeof(PVOID)];
UCHAR WrapperReservedEx[sizeof(PVOID)];
};

struct
{
UCHAR MacReserved[4*sizeof(PVOID)];
};
};

ULONG_PTR Reserved[2]; // For compatibility with Win95
UCHAR ProtocolReserved[1];

} NDIS_PACKET, *PNDIS_PACKET, **PPNDIS_PACKET;
typedef struct _NDIS_PACKET_OOB_DATA
{
union
{
ULONGLONG TimeToSend;
ULONGLONG TimeSent;
};
ULONGLONG TimeReceived;
UINT HeaderSize;
UINT SizeMediaSpecificInfo;
PVOID MediaSpecificInformation;

NDIS_STATUS Status;
} NDIS_PACKET_OOB_DATA, *PNDIS_PACKET_OOB_DATA;

明白了这些,再看一个宏,就明白了;
#define NDIS_OOB_DATA_FROM_PACKET(_p) \
(PNDIS_PACKET_OOB_DATA)((PUCHAR)(_p) + \
(_p)->Private.NdisPacketOobOffset)
即Packet结构里面有一个指向OOB的指针,指向OOB数据的偏移.
这样就可以得到数据包里的oob数据了.
