## DECnet configuration#config DECNET	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 (EXPERIMENTAL)"	depends on DECNET && EXPERIMENTAL	---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. config DECNET_ROUTE_FWMARK	bool "DECnet: use FWMARK value as routing key (EXPERIMENTAL)"	depends on DECNET_ROUTER && NETFILTER	help	  If you say Y here, you will be able to specify different routes for	  packets with different FWMARK ("firewalling mark") values	  (see ipchains(8), "-m" argument).
