Hi linux-bluetooth,

This series of patches manages the hardware offloading part of MSFT
extension API. The full documentation can be accessed by this link:
https://docs.microsoft.com/en-us/windows-hardware/drivers/bluetooth/microsoft-defined-bluetooth-hci-commands-and-events

Only four of the HCI commands are planned to be implemented:
HCI_VS_MSFT_Read_Supported_Features (implemented in previous patch),
HCI_VS_MSFT_LE_Monitor_Advertisement,
HCI_VS_MSFT_LE_Cancel_Monitor_Advertisement, and
HCI_VS_MSFT_LE_Set_Advertisement_Filter_Enable.
These are the commands which would be used for advertisement monitor
feature. Only if the controller supports the MSFT extension would
these commands be sent. Otherwise, software-based monitoring would be
performed in the user space instead.

Thanks in advance for your feedback!

Archie

Changes in v2:
* Add a new opcode instead of modifying an existing one
* Also implement the new MGMT opcode and merge the functionality with
the old one.
