Forum thread with WIP link which is the apparent resolution.

In the forum thread @jow- was mentioned as knowledgeable on subject. Essence - when dsa user ports are excluded from soft offload abusing latest fw4 code - offloaded forwarding starts to happen. Which avoids and softly points to a bug or shortage in particular DSA driver set.

Software flow offloading is broken on WRT32X too. Similar internal hardware so would be expected, but just to confirm. Tested a few versions with 5.15, as far back as 23.05.0.

You can avoid suspected buggy DSA driver using latest firewall4 code https://forum.openwrt.org/t/wrt1200ac-does-not-work-softoffloading/207507/12?u=brada4 I.e. offload discharges to bridge interface additionally keeping LAN ARP and wifi roaming undisturbed by itself, still doing heaviest packet re-addressing part fast.
