Bug description:
  As described in the following links, there seems to be a fragmentation
  support in OVN by now.

  https://bugs.launchpad.net/networking-ovn/+bug/1838405

  It's disabled by default, and it would be nice if the charms can make
  an intelligent decision to enable it if conditions are met or having a
  config knob at least would be nice.

  > it requires a specific kernel
  > version for it to work (upstream >= 5.2).

  > At earlier versions of this patch we thought about having networking-ovn
