Excellent news. Many thanks for sharing the details of the steps that
you have taken.

The issue of firmware images for EL6 is a little bit "messy" and gets
rather complicated when attempting to provide the ELRepo Project's
kernel-{lt|ml}-firmware packages. As I am sure you have seen, we
recommend using the distro firmware package for normal use. If there
is a deficiency in the kernel-firmware package when using it with
kernel-{lt|ml}, then we would normally recommend manually copying the
required files into the target system's /lib/firmware/ directory
structure.

In this case, both the messages output and the module's source code
were not particularly helpful . . .

Now that you know the files required, it would be a straightforward
RPM packaging task to create your own local package to provide those
files. But is it actually worth the effort?

Alan.
