Subject: [PATCH v1 0/2] btusb: Introduce the use of vendor extension(s)

Hi Marcel and Luiz,

The standard HCI does not provide commands/events regarding to
advertisement monitoring with content filter while there are few vendors
providing this feature. Chrome OS BT would like to introduce the use of
vendor specific features where Microsoft vendor extension is targeted at
this moment.

Chrome OS BT would like to utilize Microsoft vendor extension's
advertisement monitoring feature which is not yet a part of standard
Bluetooth specification. This series introduces the driver information for
Microsoft vendor extension, and this was verified with kernel 4.4 on Atlas
Chromebook.

Thanks
Miao

Changes in v1:
- Add a bit mask of driver_info for Microsoft vendor extension.
- Indicates the support of Microsoft vendor extension for Intel
9460/9560 and 9160/9260.
- Add fields to struct hci_dev to facilitate the support of Microsoft
vendor extension.
- Add vendor_hci.h to facilitate opcodes and packet structures of vendor
extension(s).
- Add opcode for the HCI_VS_MSFT_Read_Supported_Features command from
Microsoft vendor extension.
- Issue a HCI_VS_MSFT_Read_Supported_Features command upon
hci_dev_do_open and save the return values.
