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.
