iwlwifi test on X1 Yoga: “MicrocodeSW error”

Hi all,

just as a testing point, I rebuild -stable yesterday and just 
tried iwlwifi for the first time on an Lenovo X1 Yoga, and got a 
“Microcode SW error“

I had to manually load if_iwlwifi, without it I got no wlan0, 
if_iwm was automatically loaded first I think.

I’m switching back to iwm, just wanted to know if it is working 
already. If someone needs more info just ask.

This is just an information point, I do not need iwlwifi, iwm 
works for now.

Cheers, Mathias

from /etc/rc.conf
