The exact behavior depends on the hardware revision, but some older versions would likely end up using the Data frame rules for decrypting the management frames and as such, would require software workaround that re-encrypt the frame using Data frame rules and then make the frame go the normal software decryption. While this is possible to implement, I have not bothered to do so yet and don't know how much interest there would be for such a feature at this point. This would also require some new APIs from mac80211 to allow re-use of CCMP code. -- Jouni Malinen PGP id EFC895FA -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
