Without hacking the firmware config

 /lib/firmware/brcm/brcmfmac43430-sdio.raspberrypi,3-model-b.txt

it does not work for brcmfmac ... btw. on an intel laptop cfg80211 does its job
well and the command ``iw reg get`` lists the global as well as the phy#0
configuration ... on the raspberry only the global one is shown:

bash> iw reg get 
global

... here with the hacked firmware config as otherwise I do not have network at
all.
