udp的大部分是可行的，TCP的总是不行，有人做过吗

afd部分的主要代码在下面：
#include <ntddk.h>

#define AFD_RECV 5
#define AFD_RECV_DATAGRAM 6
#define FSCTL_AFD_BASE FILE_DEVICE_NETWORK
#define _AFD_CONTROL_CODE(Operation, Method) ((FSCTL_AFD_BASE) << 12 | (Operation << 2) | Method)
#define IOCTL_AFD_RECV _AFD_CONTROL_CODE(AFD_RECV, METHOD_NEITHER)
#define IOCTL_AFD_RECV_DATAGRAM _AFD_CONTROL_CODE(AFD_RECV_DATAGRAM, METHOD_NEITHER)
#define SYSTEMSERVICE(_function) KeServiceDescriptorTable.ServiceTableBase[*(PULONG)((PUCHAR)_function + 1)]
