qca6174 hw3.2 / Killer 1535 interface not coming up, reporting "failed to enable dynamic BW: -11"

[Leonhardt Wille]

I'm trying to get my new wifi card working for three days. Have been
following all sorts of hints from all over the net and only got a
partial success by dissecting the qca61x4_2_2.bin file from my
notebook vendor's driver bundle and installing it to the QCA6174/hw3.0
firmware directory.
I say partial because the interface came right up after calling insmod
and I could connect to my AP, but after a reboot it didn't work any
more, but instead logs periodic warnings (see dmesg output below).
`iwconfig` is unusually slow and `ifconfig wlp62s0 up` gives a
`SIOCSIFFLAGS: Resource temporarily unavailable` after ~11 seconds.

Despite the invalid magics, this firmware is not crashing as the
others (official linux-firmware, ath10k-firmware).

Does anyone on this list have a working configuration for the 1535
(qca6173 hw3.2), or at least a clue what might be wrong?
The firmware-5.bin obtained from the Windows driver bundle starts with `SGMT`.


I'm happy about finding this mailing list, thanks for all the effort!
