Not in ath9k - it is in net/mac80211/tx.c. The function 
ieee80211_parse_tx_radiotap will inspect the radiotap header and set the flag 
IEEE80211_TX_CTRL_RATE_INJECT if it was able to retrieve some rates from it.

And ieee80211_tx_h_rate_ctrl will just not try to calculate new rates when 
they were already injected by the radiotap header (see 
IEEE80211_TX_CTRL_RATE_INJECT).

Kind regards,
