I'm not Jouni... But encryption and decryption of the data is usually
handled by the wifi hardware. However, most mac80211-based drivers
provide a module parameter (swenc, nohwcrypt, ...) which - when set -
will let the driver/stack fallback to software encryption and decryption
[no more firmware/hardware will be involved].
You can find the entry code which handles AES encryption
for all mac80211-based driver under
It's called as part of the tx path from: ieee80211_tx_h_encrypt
