[PATCH] ath9k: Fix TX status reporting for retries and MCS index
From: Jouni Malinen <hidden>
Date: 2008-12-15 13:45:08
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.
