Subject: [PATCH 1/5] Bluetooth: btusb: Support public address configuration
|
|
for MediaTek Chip.
|
|
|
|
The MediaTek chip support vendor specific HCI command(0xfc1a) to
|
|
change the public address. Add hdev->set_bdaddr handler for MediaTek
|
|
Chip. After doing a power cycle or MediaTek Bluetooth reset, BD_ADDR
|
|
will bring back the original one.
