Packages tun provides utilities for tun.

tun包提供创建tun设备的方法，以及监听tun，将数据解析为tcp/udp数据的方法。

tun 工作在第三层 IP层上。

我们基本上抄了 xjasonlyu/tun2socks, 因此把GPL证书放在了本包的文件夹中

本来最好是直接import的，但是目前（22.12.18）tun2socks的最新代码还没有打tag，而老代码又不可用，所以只能先复制过来。

windows中, 需要从 https://www.wintun.net/ 下载 wintun.dll 放到vs可执行文件旁边

func Listen(dev device.Device, tcpFunc func(netLayer.TCPRequestInfo), udpFunc func(netLayer.UDPRequestInfo)) (closer io.Closer, err error)

非阻塞

func Open(name string) (device.Device, error)

若name为空则会返回错误

type StackCloser struct {
	*stack.Stack
}

func (sc *StackCloser) Close() error

type UdpMsgConn struct {
	net.PacketConn
	RealTarget netLayer.Addr
	// contains filtered or unexported fields
}

Wraps net.PacketConn and implements MsgConn

func (mc *UdpMsgConn) Close() error

func (mc *UdpMsgConn) CloseConnWithRaddr(raddr netLayer.Addr) error

func (mc *UdpMsgConn) Fullcone() bool

func (mc *UdpMsgConn) ReadMsg() ([]byte, netLayer.Addr, error)

func (mc *UdpMsgConn) WriteMsg(p []byte, peera netLayer.Addr) error
