Not sure what the motivation is to include a pure added feature to a
stable tree. But if you truly want the patch, then there were a couple
follow up fixes over the years. At least the following look like patches
to code that would be problematic in 5.4.y as well:

cd9b50adc6bb ("net/sched: ets: fix crash when flipping from 'strict' to 'quantum'")
454d3e1ae057 ("net/sched: sch_ets: properly init all active DRR list handles")
de6d25924c2a ("net/sched: sch_ets: don't peek at classes beyond 'nbands'")
c062f2a0b04d ("net/sched: sch_ets: don't remove idle classes from the round-robin list")
d62b04fca434 ("net: sched: fix ets qdisc OOB Indexing")
1a6d0c00fa07 ("net_sched: ets: Fix double list add in class with netem as child qdisc")
