Comment 5 for bug 2023764

To be more specific [1][2] in kernel-5.14.0-325.el9 triggered this issue. pyroute2 0.6.10 contains the fix[3] for it. It's spotted in Fedora[4]/Kinetic[5] before. I tested the manual backport of [3] in the impacted environment and issue is not seen. Seems we would need to do backport for it in pyroute2 package.
