Hello! You should remove only decnet from the list, not bridge.
This is two columns table.

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/
