Subject: [PATCH] mac80211: update last_tx_rate only for data frame
Date: Wed,  2 Apr 2014 12:05:09 +0800	[thread overview]
Message-ID: <1396411509-4660-1-git-send-email-yeohchunyeow@gmail.com> (raw)

Rate controller in firmware may also return the Tx Rate
used for management frame that is usually sent as lowest
Tx Rate (1Mbps in 2.4GHz). So update the last_tx_rate only
if it is data frame.

This patch is tested with ath9k_htc.
