| OVERVIEW: |
| |
| This software unit holds the implementation of the WLAN BAP modules |
| "platform independent" Data path functions. |
| |
| The functions externalized by this module are to be called ONLY by other |
| WLAN modules (HDD) that properly register with the BAP Layer initially. |
| |
| DEPENDENCIES: |
| |
| Are listed for each API below. |
