CT firmware beta-15 now has better monitor mode.
Here is the changelog note. This particular improvement does not require any driver patches as far as I know. I tested this on my 4.0.4+ kernel.
Should be useful for anyone doing sniffing with ath10k.
* Allow monitor mode to receive 'Association Request', block-ack action frames, nodata frames, TYPE-CTL frames. Previously, these were not delivered to the WMI interface, and the kernel driver is configured to drop mgmt frames in the normal RX htt datapath, so host never saw them.
This makes sniffing with ath10k a lot more useful. When no monitor devices are active, the firmware reverts to the previous behaviour. I guess the idea is that this is an optimization and keeps some un-needed frames off the host.

I'd be curious to know if anyone finds any bugs with this. It is possible that my changes could cause duplicate frames to be received in monitor mode, so please keep an eye out for that.
Thanks,
Ben
