+ * -msg_type
+ * Bits 7:0
+ * Purpose: identifies this as HTT TX completion indication
+ * -status
+ * Bits 10:8
+ * Purpose: the TX completion status of payload fragmentations descriptors
+ * Value: could be HTT_TX_COMPL_IND_STAT_OK or HTT_TX_COMPL_IND_STAT_DISCARD
+ * -tid
+ * Bits 14:11
+ * Purpose: the tid associated with those fragmentation descriptors. It is
+ * valid or not, depending on the tid_invalid bit.

+ * -tid_invalid
+ * Bits 15:15
+ * Purpose: this bit indicates whether the tid field is valid or not
+ * Value: 0 indicates valid, 1 indicates invalid
+ * -num
+ * Bits 23:16
+ * Purpose: the number of payload in this indication
+ * Value: 1 to 255
+ * -A0 = append
+ * Bits 24:24
+ * Purpose: append the struct htt_tx_compl_ind_append_retries which contains
+ * the number of tx retries for one MSDU at the end of this message
+ * Value: 0 indicates no appending, 1 indicates appending
+ * -A1 = append1
+ * Bits 25:25
+ * Purpose: Append the struct htt_tx_compl_ind_append_tx_tstamp which
+ * contains the timestamp info for each TX msdu id in payload.
+ * Value: 0 indicates no appending, 1 indicates appending
+ * -TP = MSDU tx power presence
+ * Bits 26:26
+ * Purpose: Indicate whether the TX_COMPL_IND includes a tx power report
+ * for each MSDU referenced by the TX_COMPL_IND message.
+ * The order of the per-MSDU tx power reports matches the order
+ * of the MSDU IDs.
+ * Value: 0 indicates not appending, 1 indicates appending
+ * -A2 = append2
+ * Bits 27:27
+ * Purpose: Indicate whether data ACK RSSI is appended for each MSDU in
+ * TX_COMP_IND message. The order of the per-MSDU ACK RSSI report
+ * matches the order of the MSDU IDs.
+ * The ACK RSSI values are valid when status is COMPLETE_OK (and
+ * this append2 bit is set).
+ * Value: 0 indicates not appending, 1 indicates appending
