IF I correctly understood
http://wireless.kernel.org/en/users/Drivers/iwlwifi#Firmware
Fedora is shipping at least one unnecessary firmware version compared to the
kernels used,
e.g. for
Intel® Centrino® Advanced-N 6205
IS required only iwlwifi-6000g2a-6.ucode - kernel 3.2+
and NOT iwlwifi-6000g2a-5.ucode - kernel 2.6.35+
Fedora ships whatever is in the upstream linux-firmware git repo in
the linux-firmware package. It's stand-alone. We don't tie it to the
kernel versions in Fedora. People do strange things like running
their own kernels on top of a Fedora OS install all the time.
