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@chromium.org> --- 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. drivers/bluetooth/btusb.c | 14 ++++++++++++-- include/net/bluetooth/hci_core.h | 6 ++++++ 2 files changed, 18 insertions(+), 2 deletions(-)
