Bluetooth: Differentiate LE User Pairing Responses (47c15e2b) · Commits · 戴 / test

Low Energy (LE) pairing responses must be recognized and handled differently from BR/EDR pairing responses. BR/EDR responses are handled via HCI commands by the LMP layer, and LE responses are handled by the Host. Signed-off-by:
