[PATCH] ieee80211: Drop and count duplicate data frames to remove 'replay detected' log messages
In the SoftMAC version of the IEEE 802.11 stack, not all duplicate messages are detected. For the most part, there is no difficulty; however for TKIP and CCMP encryption, the duplicates result in a "replay detected" log message where the received and previous values of the TSC are identical. This change adds a new variable to the ieee80211_device structure that holds the 'seq_ctl' value for the previous frame. When a new frame repeats the value, the frame is dropped and the appropriate counter is incremented. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: John W.
