+ tristate "DECnet Support"
+ ---help---
+ The DECnet networking protocol was used in many products made by
+ Digital (now Compaq). It provides reliable stream and sequenced
+ packet communications over which run a variety of services similar
+ to those which run over TCP/IP.
+
+ To find some tools to use with the kernel layer support, please
+ look at Patrick Caulfield's web site:
+ <http://linux-decnet.sourceforge.net/>.
+
+ More detailed documentation is available in
+ <file:Documentation/networking/decnet.txt>.
+
+ Be sure to say Y to "/proc file system support" and "Sysctl support"
+ below when using DECnet, since you will need sysctl support to aid
+ in configuration at run time.
+
+ The DECnet code is also available as a module ( = code which can be
+ inserted in and removed from the running kernel whenever you want).
+ The module is called decnet.
+
+config DECNET_ROUTER
+ bool "DECnet: router support"
+ depends on DECNET
+ select FIB_RULES
+ ---help---
+ Add support for turning your DECnet Endnode into a level 1 or 2
+ router. This is an experimental, but functional option. If you
+ do say Y here, then make sure that you also say Y to "Kernel/User
+ network link driver", "Routing messages" and "Network packet
+ filtering". The first two are required to allow configuration via
+ rtnetlink (you will need Alexey Kuznetsov's iproute2 package
+ from <ftp://ftp.tux.org/pub/net/ip-routing/>). The "Network packet
+ filtering" option will be required for the forthcoming routing daemon
+ to work.
+
+ See <file:Documentation/networking/decnet.txt> for more information.
