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,
Sven
