Help with Private Preshared Key "PPKS"

I am looking for help in adding "Private Preshared Key" PPSK with radius support to OpenWrt. There was some work started in this old thread and I've attempted to patch my build of 21.02 with the files from the github repo found here Wifi ppsk mode

My problem is that while Luci shows the correct fields the wlan interfaces no longer load. I don't see them in dmesg any longer. I'm assuming that I'm messing something up with hostapd when I patch the changes in.
It might have been possible that the wpad-basic-wolfssl might be the issue and I should do a build with the full wpad-wolfssl.
Ideas?
