ath9k: Fix TX status reporting for retries and MCS index
The count field in struct ieee80211_tx_rate does not include the final successful attempt, so only report retries here. Fix the struct ieee80211_tx_rate::idx field when MCS was used. It is supposed to be the MCS index, not an internal index to the rate control algorithm table. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.
