Ben,

I tried using your firmware on a 3.14 kernel without any luck. I don't
see any errors, but the sta never associates nor see's any ap on scan.
I followed http://www.candelatech.com/vsta.php step 4 and step 6 and
did this on OpenWrt, so the udev stuff doesn't apply.

What we really need here is for QCA to step up to the plate and fix
their firmware... or better yet open it up and let the community fix
what they can't! This is really holding ath10k and QCA988x back. We
have customers looking for alternatives after getting a rude awakening
to ath10k.

Kalle - Will QCA make some sort of statement as to what the plans are
with this firmware? Will there be updates? Will the features be merged
into a single firmware? Will it be opened up so that the community can
improve the product?

Regards,

Tim
