| 520 | ** Description HOST/CONTROLLER LIB CALLBACK API - This function is called |
| 521 | ** from the libbt-hci once it has processed/sent the prior data |
| 522 | ** buffer which core stack passed to it through transmit_buf |
| 523 | ** call earlier. |
| 524 | ** |
| 525 | ** The core stack is responsible for releasing the data buffer |
| 526 | ** if it has been completedly processed. |
| 527 | ** |
| 528 | ** Bluedroid libbt-hci library uses 'transac' parameter to |
| 529 | ** pass data-path buffer/packet across bt_hci_lib interface |
| 530 | ** boundary. The 'p_buf' is not intended to be used here |
| 531 | ** but might point to data portion in data-path buffer. |
| 532 | ** |
| 533 | ** Returns bt_hc_status_t |
