I have a script to build every commit now, but except for the first few
and the last few images, you would need various driver changes to work with them.

I can rebase my firmware changes so that hopefully all (or at least most) of the
images will work on standard kernels, but it may be a few days before I
can get that done.

In the meantime, please try these two:

Compiled from original source received from QCA:

http://www.candelatech.com/downloads/firmware-2-community-commit-0-207ce4b.bin

It appeared to me that that code had a regression, so next commit fixed
that:

http://www.candelatech.com/downloads/firmware-2-community-commit-1-5717c65.bin

If either of these work with DFS, then some change I made later broke it, and I can
build the rest of the images so we can figure out where.

Thanks,
Ben
