The Linux kernel configuration item CONFIG_DUMMY
has multiple definitions:
drivers/net/Kconfig
The configuration item CONFIG_DUMMY:

This is essentially a bit-bucket device (i.e. traffic you send to this device is consigned into oblivion) with a configurable IP address. It is most commonly used in order to make your currently inactive SLIP address seem like a real address for local programs. If you use SLIP or PPP, you might want to say Y here. It won't enlarge your kernel. What a deal. Read about it in the Network Administrator's Guide, available from http://www.tldp.org/docs.html#guide.
To compile this driver as a module, choose M here: the module will be called dummy.

This is essentially a bit-bucket device (i.e. traffic you send to this device is consigned into oblivion) with a configurable IP address. It is most commonly used in order to make your currently inactive SLIP address seem like a real address for local programs. If you use SLIP or PPP, you might want to say Y here. Since this thing often comes in handy, the default is Y. It won't enlarge your kernel either. What a deal. Read about it in the Network Administrator's Guide, available from http://www.linuxdoc.org/docs.html#guide.
If you want to compile this as a module ( = code which can be inserted in and removed from the running kernel whenever you want), say M here and read Documentation/modules.txt. The module will be called dummy. If you want to use more than one dummy device at a time, you need to compile this driver as a module. Instead of 'dummy', the devices will then be called 'dummy0', 'dummy1' etc.
