数据结构
struct	packet_file_header
	Header of a libpcap dump file. More...
struct	sf_pkthdr
	Header associated to a packet in the driver's buffer when the driver is in dump mode. Similar to the bpf_hdr structure, but simpler. More...
struct	_INTERNAL_REQUEST
	Stores an OID request. More...
struct	_PACKET_RESERVED
	Contains a NDIS packet. More...
struct	_DEVICE_EXTENSION
	Port device extension. More...
struct	__CPU_Private_Data
	Kernel buffer of each CPU. More...
struct	_OPEN_INSTANCE
	Contains the state of a running instance of the NPF driver. More...
struct	PacketHeader
	Structure prepended to each packet in the kernel buffer pool. More...
定义

#define	BIOCSWRITEREP7413
	IOCTL code: set number of physical repetions of every packet written by the app.
#define	BIOCSMINTOCOPY7414
	IOCTL code: set minimum amount of data in the kernel buffer that unlocks a read call.
#define	BIOCSETOID2147483648
	IOCTL code: set an OID value.
#define	BIOCQUERYOID2147483652
	IOCTL code: get an OID value.
#define	BIOCSETDUMPFILENAME9029
	IOCTL code: set the name of a the file used by kernel dump mode.
#define	BIOCGEVNAME7415
	IOCTL code: get the name of the event that the driver signals when some data is present in the buffer.
#define	BIOCSENDPACKETSNOSYNC9032
	IOCTL code: Send a buffer containing multiple packets to the network, ignoring the timestamps.
#define	BIOCSENDPACKETSSYNC9033
	IOCTL code: Send a buffer containing multiple packets to the network, considering the timestamps.
#define	BIOCSETDUMPLIMITS9034
	IOCTL code: Set the dump file limits.
#define	BIOCISDUMPENDED7411
	IOCTL code: Get the status of the kernel dump process.
#define	BIOCISETLOBBEH7410
	IOCTL code: set the loopback behavior.
#define	BIOCSETEVENTHANDLE7920
	This IOCTL passes the read event HANDLE allocated by the user (packet.dll) to kernel level.

#define	NDIS_FLAGS_SKIP_LOOPBACK_W2K0x400
	This is an undocumented flag for NdisSetPacketFlags() that allows to disable loopback reception.
#define	TCPDUMP_MAGIC0xa1b2c3d4
	Libpcap magic number. Used by programs like tcpdump to recognize a driver's generated dump file.

	Major libpcap version of the dump file. Used by programs like tcpdump to recognize a driver's generated dump file.
#define	PCAP_VERSION_MINOR4
	Minor libpcap version of the dump file. Used by programs like tcpdump to recognize a driver's generated dump file.
#define	NPF_DISABLE_LOOPBACK1
	Tells the driver to drop the packets sent by itself. This is usefult when building applications like bridges.
#define	NPF_ENABLE_LOOPBACK2
	Tells the driver to capture the packets sent by itself.
#define	RESERVED(_p)((PPACKET_RESERVED)((_p)->ProtocolReserved))
	Macro to obtain a NDIS_PACKET from a PACKET_RESERVED.
#define	TRANSMIT_PACKETS256
	of packets that can be transmitted at the same time or with a single call to NdisSendPackets.
