Tested out the patch on clean 4.18.5 kernel source; it works as expected. I also tried out proprietary firmware, but I couldn't reproduce a problem mentioned in https://marc.info/?l=linux-wireless&m=153504546924558&w=2 . The proprietary firmware works very sluggishly on my card (BCM4306) and doesn't stand for practical use for unknown reason. -- kabe
