Bluetooth: Use extended LE Connection if supported
This implements extended LE craete connection and enhanced LE conn complete event if the controller supports. For now it is as good as legacy LE connection and event as no new features in the extended connection is handled. < HCI Command: LE Extended Create Connection (0x08|0x0043) plen 26 Filter policy: White list is not used (0x00) Own address type: Public (0x00) Peer address type: Random (0x01) Peer address: DB:7E:2E:1D:85:E8 (Static) Initiating PHYs: 0x01 Entry 0: LE 1M Scan interval: 60.000 msec (0x0060) Scan window: 60.000 msec (0x0060) Min connection interval: 50.00 msec (0x0028) Max connection interval: 70.00 msec (0x0038) Connection latency: 0 (0x0000) Supervision timeout: 420 msec (0x002a) Min connection length: 0.000 msec (0x0000) Max connection length: 0.000 msec (0x0000) > HCI Event: Command Status (0x0f) plen 4 LE Extended Create Connection (0x08|0x0043) ncmd 2 Status: Success (0x00) > HCI Event: LE Meta Event (0x3e) plen 31 LE Enhanced Connection Complete (0x0a) Status: Success (0x00) Handle: 3585 Role: Master (0x00) Peer address type: Random (0x01) Peer address: DB:7E:2E:1D:85:E8 (Static) Local resolvable private address: 00:00:00:00:00:00 (Non-Resolvable) Peer resolvable private address: 00:00:00:00:00:00 (Non-Resolvable) Connection interval: 67.50 msec (0x0036) Connection latency: 0 (0x0000) Supervision timeout: 420 msec (0x002a) Master clock accuracy: 0x00 @ MGMT Event: Device Connected (0x000b) plen 40 LE Address: DB:7E:2E:1D:85:E8 (Static) Flags: 0x00000000 Data length: 27 Name (complete): Designer Mouse Appearance: Mouse (0x03c2) Flags: 0x05 LE Limited Discoverable Mode BR/EDR Not Supported 16-bit Service UUIDs (complete): 1 entry Human Interface Device (0x1812) Signed-off-by: Jaganath Kanakkassery <jaganathx.kanakkassery@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
