Title:
  Network namespaces support for non-IP suddenly missing

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I run 16.04, and I keep daily track of all dist-upgrades. Yesterday (3
  july 2018) there was an upgrade, and it must have been a kernel
  upgrade, because my machine had rebooted (which I make it do
  automatically if needed).

  From today, the system tests on my project have stopped working (C 
development). These system tests do the following: using the 'ip' command, they 
set up several network namespaces, in which I run several executables 
concurrently, that exchange network messages with each other. The namespaces 
that use IP have kept on working, while the ones that don't (I'm implementing 
an ethernet network packet structure of my own) have stopped working. I've done 
the same tests on my laptop, which is also a 16.04, on which I haven't done the 
upgrade (and I'm very hesitant to do so now, because this is my bread and 
butter), and there they work still.
