I've tested:
https://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211.git/commit/?id=33d915d9e8ce811d8958915ccd18d71a66c7c495

And applied it to OpenWrt's (v4.19 based) backports package:
https://github.com/openwrt/openwrt/pull/2139/commits/425ab52a0d451938c87ebafdf247b86fa563ad36

Yes, QCA9984/ ath10k[1] as 4addr/ WDS-AP was affected starting with
(backports-) kernel 4.18 and above. I've tested v1 and the version
you merged with
https://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211.git/commit/?id=33d915d9e8ce811d8958915ccd18d71a66c7c495
both versions of this patch fix the problem for me and survived a
slightly over 2 day stress test.
