$ cat /proc/version
Linux version 5.8.0-59-generic (buildd@bos02-arm64-044) (gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #66~20.04.1-Ubuntu SMP Thu Jun 17 11:13:01 UTC 2021

Also tried latest iproute2-next branch (@3e26254) just in case it is a userspace issue (unlikely given Christian's "good" example), and verified it is still an issue.
