[PATCH] mac80211: Turn off meaningless TKIP message when software WEP encryption is used

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For drivers that do no hardware encryption/decryption, WEP encryption
works as long as IEEE80211_HW_INCLUDE_IV is not set in the flags variable.
With WPA encryption and IEEE80211_HW_INCLUDE_IV not set, the logs are full
of TKIP decrypt failure messages. Despite the messages, RX is working.
This patch turns off the message for this case.
