QCA6174 hw2.1 firmware, take two?

[Enrico Tagliavini]

Hi Gregor,

yes it works, but bluetooth is broken (for me at least, does it work for you?).

Also this is just a place holder solution, this needs to get into
mainline linux kernel and firmware must be available linux-firmware
package.

I'm ok to patch my own kernel for a very short time, but in the long
run I'd rather switch to another wireless adapter (for how much this
can upset me). Don't get me wrong, no hard feelings, but I'll be on
the road in a month or two and I need to have no potential problems
since the time for fixing them will be short if any.

Best regards.
