Subject[PATCH v5 3/3] Bluetooth: btusb: Indicate Microsoft vendor extension for Intel 9160/9260
Date
This adds a bit mask of driver_info for Microsoft vendor extension and
indicates the support for Intel 9160/9260. This was verified with Intel
ThunderPeak BT controller where msft_opcode is 0xFC1E.

Changes in v5:
- Extract the changes on btusb as a different commit.

Changes in v4:
- Introduce CONFIG_BT_MSFTEXT as a starting point of providing a
framework to use Microsoft extension
- Create include/net/bluetooth/msft.h and net/bluetooth/msft.c to
facilitate functions of Microsoft extension.

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().

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.
