DECnet is an obsolete network protocol that receives more attention

It has been "Orphaned" in kernel since 2010. The iproute2 support
for DECnet was dropped in 5.0 release. The documentation link on
Sourceforge says it is abandoned there as well.

Leave the UAPI alone to keep userspace programs compiling.
This means that there is still an empty neighbour table
for AF_DECNET.

The table of /proc/sys/net entries was updated to match
current directories and reformatted to be alphabetical.

Hi,

this breaks userspace. Some projects include linux/dn.h:

  https://codesearch.debian.net/search?q=include.*linux%2Fdn.h&literal=0


I found Trinity fails to build:
net/proto-decnet.c:5:10: fatal error: linux/dn.h: No such file or directory
     5 | #include <linux/dn.h>



Should we provide the above as empty files?

thanks,
