| 30 | * @brief Provide functions to send host->target HTT messages. |
| 31 | * @details |
| 32 | * This file contains functions related to host->target HTT messages. |
| 33 | * There are a couple aspects of this host->target messaging: |
| 34 | * 1. This file contains the function that is called by HTC when |
| 35 | * a host->target send completes. |
| 36 | * This send-completion callback is primarily relevant to HL, |
| 37 | * to invoke the download scheduler to set up a new download, |
| 38 | * and optionally free the tx frame whose download is completed. |
| 39 | * For both HL and LL, this completion callback frees up the |
| 40 | * HTC_PACKET object used to specify the download. |
| 41 | * 2. This file contains functions for creating messages to send |
| 42 | * from the host to the target. |
