I added this info to the commit log in the pending branch. Oh, we should still add ATH10K_FW_FEATURE_NO_ADHOC so that we can disable ad-hoc on 10.x firmwares.

If you give me some way to advertise my CT 10.1 firmware supports ADHOC mode in the upstream driver then there will be one more firmware variant that works with IBSS in stock kernels Maybe a feature flag 'ATH10K_FW_FEATURE_SUPPORTS_ADHOC' ? You can special case older firmware that is known to support ADHOC but has no feature flag for it. And new firmware could add the feature flag as needed.

Hello,
I have successfully installed the latest version of ath10k driver from
backports.
However, I have some difficulties on configuring wpa_supplicant for IBSS VHT
mode.
Looked at wpa_supplicant configuration file, but I couldn't found any option
related to explicit setting VHT (though I've found disable_vht instead)
Sorry for annoying questions, but can you help this out?
At least you could let me know your configuration of wpa_supplicant.
supplicant by default setup wildest BW, no special parameter required
for IBSS VHT
network = {
ssid=ibss
mode=1
key_mgmt=NONE
frequency=5180
}
Just use latest version of wpa_supplicant.
next check you have 80MHz BW
iw wlan0 info
Make sure you compile supplicant with this option enabled:
CONFIG_IBSS_RSN=y
I think only particular firmware versions are doing to do IBSS as well.
Thanks,
Ben
