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 v2:
- Define struct msft_vnd_ext and add a field of this type to struct
hci_dev to facilitate the support of Microsoft vendor extension.
- Issue a HCI_VS_MSFT_Read_Supported_Features command with
__hci_cmd_sync() instead of constructing a request.
