Re: [PATCH] Bluetooth: btrtl: Ask ic_info to drop firmware

Hi Hilda,

The MSFT extension has a HCI_VS_MSFT_Read_Supported_Features command. The AOSP extension has a read capability cmd too.
https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/microsoft-defined-bluetooth-hci-commands-and-events#hci_vs_msft_read_supported_features
https://source.android.com/devices/bluetooth/hci_requirements#vendor-specific-capabilities
If commands did not support, the controller should feedback event status as Unknown HCI Command (0x01).
We can go on this way.

I am not doing trial-and-error programming here. I rather better disable any extensions for Realtek devices altogether.

Regards

Marcel
