| * @file htt_h2t.c |
| * @brief Provide functions to send host->target HTT messages. |
| * @details |
| * This file contains functions related to host->target HTT messages. |
| * There are a couple aspects of this host->target messaging: |
| * 1. This file contains the function that is called by HTC when |
| * a host->target send completes. |
| * This send-completion callback is primarily relevant to HL, |
| * to invoke the download scheduler to set up a new download, |
| * and optionally free the tx frame whose download is completed. |
| * For both HL and LL, this completion callback frees up the |
| * HTC_PACKET object used to specify the download. |
| * 2. This file contains functions for creating messages to send |
| * from the host to the target. |
