I noticed this line in the system log after boot:
"May 14 14:41:08 ubuntu kernel: [    8.677878] NET: Registered protocol family 40"
I tried to find out what protocol that was, and eventually determined that the IANA thinks it's the IL protocol, which is deprecated and unusual in any case. Protocol number 40 doesn't appear in the expected config or alias files (for modprobe in /etc or /etc/modprobe.d/). Enabling a dead protocol without being told seems to be a thing an OS shouldn't be doing.

More context for the log line is below:
