wlan0 disappears on pi zero w after install (6.1.y and 5.15.y)

[r1tr1t]

I've been trying to get nexmon firmware working on a pi zero w for the last week or so. I've followed all the steps in README using both 5.15.92+ and the stock 6.1.21+ kernel for Raspbian bullseye. I have been attempting to install bcm43430a1/7_45_41_46

I got through all steps, no issues compiling, but as soon as make install-firmware finishes, my wlan0 interface is gone. make && make install nexutil but that doesn't seem to be any help and the suggested nexutil -m0 does nothing but dump hex messages to the console. I saw in #561 that you had been able to get monitor mode working successfully on bcm43430a1, I was wondering if you could share any guidance or special steps that might ease my struggles.

I'll add logs tomorrow morning if I remember, just don't feel like starting the build process over again at this hour.
