/**
 * @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.
