There is no visible difference in how the two versions of the manpage
render.

Title:
  [jammy/mantic] ftbfs due to build-time incompatibility with updated
  openvswitch

Status in ovn package in Ubuntu:
  Invalid
Status in ovn source package in Jammy:
  Fix Committed
Status in ovn source package in Mantic:
  Fix Committed

Bug description:
  [Impact]
  ovn package currently FTBFS due to changes in the openvswitch package after recent security updates - doc tooling in the openvswitch source package that ovn uses has changed.

  [Test Case]
  Build ovn package in mantic or jammy
  Build fails:

  make[2]: *** No rule to make target
  '/home/ubuntu/ovn/b/ovn-22.03.3/ovs/python/build/soutil.py', needed by
  'manpages.mk'.  Stop.

  Confirm manpages are built properly with the new pacakge.

  [Where problems could occur]
  The proposed patches change the part of the build process uses to generate documentation (manpages), so we need to make sure the new package actually have manpages properly generated.

  [Original bug report]
  make[2]: *** No rule to make target '/home/ubuntu/ovn/b/ovn-22.03.3/ovs/python/build/soutil.py', needed by 'manpages.mk'.  Stop.

  For jammy we need [0].
  For mantic we need to drop d/p/revert-ovs-python-build-rename.patch
