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.
And the documentation link on Sourceforge says it is abandoned there.

It was pretty much obsolete when I was writing ethernet drivers
in the early 1990's.
Sort of surprising support ever got into Linux in the first place!

Remember it requires the ethernet MAC address be set to a
locally assigned value that is the machine's 'node number'.

Does this remove some/most/all of the [gs]et_sockopt() calls
where the length is ignored/
