TX duration output of tx_stats in debugfs and station dump had big

So are you sure you picked the most accurate one of the two? :)

Hi Toke,
Yes.
Now for ath10k, there are two ways to get tx duration output.
One is got from tx_stats in debugfs reported by firmware. It is a total
value including all the frames which created by host and firmware sent
to the peer.
And the second is calculated from
ath10k_htt_rx_tx_compl_ind()-->ieee80211_sta_register_airtime(), here
the tx duration just includes the data frames sent from host to the
peer.
So the first value is preferable for station dump.
Thanks.
Lei
