From da027ca00a48715364da9a94d4b663029add528d Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Mon, 15 Dec 2008 15:44:53 +0200 Subject: [PATCH] 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.
