I could try building a set of binaries and let you bisect the problem, perhaps.

This might take a bit of your time, but if you are willing, I will write a script
to create firmware binaries for each of my commits so you can do a manual
bisect.

I also think that the '2-1' part of the upstream 10.1 firmware is not in the source code
QCA made available to me, so there may be upstream fixes I have not seen, and possibly
part of that enables/fixes DFS.

I am not aware of any changes in my firmware that should have broken
DFS, but of course with 100+ commits, I could have easily added regressions...

Thanks,
Ben
