Hi Miao-chen, > This adds a bit mask of driver_info for Microsoft vendor extension and > indicates the support for Intel 9460/9560 and 9160/9260. See > https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/ > microsoft-defined-bluetooth-hci-commands-and-events for more information > about the extension. This was verified with Intel ThunderPeak BT controller > where msft_vnd_ext_opcode is 0xFC1E. > > Signed-off-by: Miao-chen Chou <mcchou@xxxxxxxxxxxx> > --- > > Changes in v3: > - Create net/bluetooth/msft.c with struct msft_vnd_ext defined internally > and change the hdev->msft_ext field to void*. > - Define and expose msft_vnd_ext_set_opcode() for btusb use. > - Init hdev->msft_ext in hci_alloc_dev() and deinit it in hci_free_dev(). so I spent some cycles on thinking about on how we can have this nice and cleanly without putting too much into the core stack or hci_dev. I took your patches and converted them a little bit into how I would do it. Please have a look. Regards Marcel
