    386 ** Function         bta_dm_co_ble_io_req
    387 **
    388 ** Description      This callout function is executed by DM to get BLE IO capabilities
    389 **                  before SMP pairing gets going.
    390 **
    391 ** Parameters       bd_addr  - The peer device
    392 **                  *p_io_cap - The local Input/Output capabilities
    393 **                  *p_oob_data - TRUE, if OOB data is available for the peer device.
    394 **                  *p_auth_req -  Auth request setting (Bonding and MITM required or not)
    395 **                  *p_max_key_size - max key size local device supported.
    396 **                  *p_init_key - initiator keys.
    397 **                  *p_resp_key - responder keys.
    398 **
    399 ** Returns          void.
