Hi Leon,

In addition to Alan's reply...

I backported the ath3k bluetooth driver from kernel-3.10 for el6, and as 
part of that I also packaged the firmware for it (above), ath3k-firmware.

I'm pretty sure the driver I backported from kernel-3.10 did not require 
these additional files so this looks like a new requirement introduced 
in a more recent kernel.

To date we haven't attempted to package additional firmwares for our 
elrepo kernel offerings (kernel-lt and kernel-ml) as things can quickly 
start to get messy, as you've already identified, with package conflicts.

I'm open to suggestions, but so far we have pretty much left it to users 
to grab the firmware files they require and manually install them as you 
have done here. Packaging the linux firmware git tree has the potential 
to cause more problems than it solves.
