Help text

TUN/TAP provides packet reception and transmission for user space programs. It can be viewed as a simple Point-to-Point or Ethernet device, which instead of receiving packets from a physical media, receives them from user space program and instead of sending packets via physical media writes them to the user space program.

When a program opens /dev/net/tun, driver creates and registers corresponding net device tunX or tapX. After a program closed above devices, driver will automatically delete tunXX or tapXX device and all routes corresponding to it.

Please read Documentation/networking/tuntap.txt for more information.

To compile this driver as a module, choose M here: the module will be called tun.

If you don't know what to use this for, you don't need it.
