But drivers like ath10k updates the tx status from the skb except txrate, txrate will be updated from a different path, peer stats. Using ieee80211_tx_status_ext() in two different paths - (one for the stats, one for the tx rate) will duplicate the stats. To avoid this stats duplication, ieee80211_tx_rate_update() is implemented.
