taken a wrong turn straight into la-la land.

Not so much newer firmware, but I used a different chip when
implementing the multi-scheduled scan patches. I tried some other
devices, but not the bcm4343{0,8}. Now as far as I can see over here the
brcmfmac43430-sdio.bin is not built with gscan support so it should just
return firmware errorcode, ie. -23. So it would be interesting to see
what firmware has to say. Can you load the driver with
ignore_probe_fail=1 and dump the forensics file in debugfs.
