Well:
$ dmesg | grep r8712u
[  380.529042] r8712u: module is from the staging directory, the quality 
is unknown, you have been warned.
[  380.530516] usbcore: registered new interface driver r8712u

But still it does not detect my fry's FR-300 USB dongle.

I am not going to go through the git kernel sources because I do not 
know what I will  end up with
as far other parts of the kernel. They state clearly that the driver 
that has been patched to work
with this dongle must be built on the git kernel source.

Guess I have to wait until fedora 30? :) :)
