In 'ath10k_htt_rx_tx_compl_ind()', int status = MS(resp->data_tx_completion.flags, HTT_DATA_TX_STATUS); actually is int status = (((resp->data_tx_completion.flags) & 0x07) >> 0); which can't be equal to HTT_DATA_TX_STATUS_DOWNLOAD_FAIL (128) regardless of the 'data_tx_completion.flags' value. This is most likely a weird (but I have no clue how serious it may be) bug. Dmitry
