Remove DECnet support from kernel
stable inclusion from stable-v4.19.286 commit 3e77bbc87342841db66c18a3afca0441c8c555e4 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7J5UF CVE: NA -------------------------------- commit 1202cdd6 upstream. DECnet is an obsolete network protocol that receives more attention from kernel janitors than users. It belongs in computer protocol history museum not in Linux kernel. 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.
