-Subject: [PATCH] ath10k: fix recent bandwidth conversion bug
-
-The commit "cfg80211: make RATE_INFO_BW_20 the default" changed
-the index of RATE_INFO_BW_20, but the updates to ath10k missed
-the special bandwidth calculation case in
-ath10k_update_per_peer_tx_stats().
-
-This will fix below warning,
