Closed requested to merge sliwkr/alpine-conf:exclude-b43 into master
select_firmware_pkgs creates a list of addional
linux-firmware-<module> to be installed based on
/sys/module/<module> during 'sys' installation. Exclude missing b43 if it's found there.
I am not sure if this should include b43legacy as well https://wireless.wiki.kernel.org/en/users/Drivers/b43#Supported_devices
Tested on a device with Broadcom BCM4313 adapter
