Re: Request for testing: Raspberry Pi 3 WiFi testing

Hello,

I can confirm that the current kernel-4.19-10-300 re-enables the wifi on
an RPi 3B for Fedora 29. I was on 4.19.7 without any wifi device
noticeable by nmcli; ran dnf upgrade to latest kernel and the wifi is
now showing and connecting as expected without any further configuration
needed.
