QCA6174 hw2.1 firmware, take two?

[Enrico Tagliavini]

Hi again,

ok this was dumb.... I forgot to assemble back the firmware and I
realized it just after sending out the previous email (that's why the
driver was complaining about the invalid magic).

Sorry for the noise, I apologize.

Hope to see this fixed in upstream Linux kernel soon.

Best regards.

Enrico.


P.S.: this is another Alienware 15 like Gabriele's. I think they all
ship with such a WiFi. Just pointing it out since Dell now is even
shyly suggesting to try out Linux

Alienware, but still...)
