I have some good news. This most recent test driver works great on WRT3200 by default.
The bad news is that the mwlwifi options: feature=0x30 setting is specifically what is causing the boot loop. So for whatever the reason, WRT3200/32X does not like that option and puts the OpenWrt OS into a continuous boot loop.
I hope this information is helpful in digging into a more specific area of code. I believe that it may narrow things down a bit.
My TV sees the wifi network with wpa3 but strangely it cannot connect, the phone supports 5Ghz but does not support this security standard but it does not see the wifi network either, how do devices that do not support this standard behave?
I have not tried it. I have no access to my WRT3200ACM right now.
My comment was just meant as testing advice, that with the earlier/original unpatched driver, WPA3 may seem to work for some time with just a single WPA3 enabled device being connected, but the driver may crash later when there are multiple devices connected with varying WPA2 & WPA3 capabilities. So, purely testing WPA3 may not be quite enough.
(I used WRT3200ACM to some extent in 2017-2021, but have largely abandoned it since then.)
I had no issues with default mwlwifi options. However, I did end up having drastic performance issues (WRT3200) with the mwlwifi options: feature=0x30 setting.
It had seemed good initially, but after a small amount of time it started to take 30-60 seconds for any web pages to load, including the local network for the router webui. Some web sites even showed up as a blank white page, empty.
So while the driver loads now without causing a boot loop, the 0x30 option ended up being very problematic.
I ended up removing the option and using the same driver, everything is running great.
