8	  The DECnet networking protocol was used in many products made by
9	  Digital (now Compaq).  It provides reliable stream and sequenced
10	  packet communications over which run a variety of services similar
11	  to those which run over TCP/IP.
12
13	  To find some tools to use with the kernel layer support, please
14	  look at Patrick Caulfield's web site:
15	  <http://linux-decnet.sourceforge.net/>.
16
17	  More detailed documentation is available in
18	  <file:Documentation/networking/decnet.rst>.
19
20	  Be sure to say Y to "/proc file system support" and "Sysctl support"
21	  below when using DECnet, since you will need sysctl support to aid
22	  in configuration at run time.
23
24	  The DECnet code is also available as a module ( = code which can be
25	  inserted in and removed from the running kernel whenever you want).
26	  The module is called decnet.

33	  Add support for turning your DECnet Endnode into a level 1 or 2
34	  router.  This is an experimental, but functional option.  If you
35	  do say Y here, then make sure that you also say Y to "Kernel/User
36	  network link driver", "Routing messages" and "Network packet
37	  filtering".  The first two are required to allow configuration via
38	  rtnetlink (you will need Alexey Kuznetsov's iproute2 package
39	  from <ftp://ftp.tux.org/pub/net/ip-routing/>). The "Network packet
40	  filtering" option will be required for the forthcoming routing daemon
41	  to work.
