Title:
  Version 0.6.7-3 is broken for "del" operations on recent kernels

Status in pyroute2 package in Ubuntu:
  Fix Released
Status in pyroute2 source package in Kinetic:
  Triaged

Bug description:
  Because of this bug upstream
  https://github.com/svinota/pyroute2/issues/923, in the versions of
  pyroute2 prior to 0.6.10, all delete operations (address, link, route,
  ...) fail with 'Operation not supported'.

  This is related to the kernel commit
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a6cec0bcd34264be8887791594be793b3f12719f

  Pyroute package has to be upgraded to a version 0.6.10 or later as
  long as the distro comes with the kernel that contains the above
  commit.

  Reproducer:

  $ sudo python3
  Python 3.10.7 (main, Sep  8 2022, 14:34:29) [GCC 12.2.0] on linux
  Type "help", "copyright", "credits" or "license" for more information.
  >>> from pyroute2 import IPRoute
  >>> IPRoute().link("add", ifname="dum0", kind="dummy")

  >>> IPRoute().link_lookup(ifname="dum0")
