CONFIG_ETHERTAP: Ethertap network tap

General informations

The Linux kernel configuration item CONFIG_ETHERTAP has multiple definitions:

Ethertap network tap found in drivers/net/Kconfig

The configuration item CONFIG_ETHERTAP:

Help text

If you say Y here (and have said Y to "Kernel/User network link driver", above) and create a character special file /dev/tap0 with major number 36 and minor number 16 using mknod ("man mknod"), you will be able to have a user space program read and write raw Ethernet frames from/to that special file. tap0 can be configured with ifconfig and route like any other Ethernet device but it is not connected to any physical LAN; everything written by the user to /dev/tap0 is treated by the kernel as if it had come in from a LAN to the device tap0; everything the kernel wants to send out over the device tap0 can instead be read by the user from /dev/tap0: the user mode program replaces the LAN that would be attached to an ordinary Ethernet device. Please read the file Documentation/networking/ethertap.txt for more information.

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

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

This driver is also available as a module ( = code which can be inserted in and removed from the running kernel whenever you want). The module will be called ethertap. If you want to compile it as a module, say M here and read Documentation/modules.txt.
