Can you explain how you even got multiple interfaces with iwlwifi? The
patch looks (superficially) correct, but I'm a bit confused.

I was only referring to wmaster0 and wlan0 as two interfaces. While a scan
is in progress the master interface (wmaster0) processes all frames related
to scanning and it happened to me that data-frames got dropped on wmaster0
(which is obviously correct) and due to the frame control being modified
wlan0 was not able to process the frame correctly anymore.
