Please include linux-wireless (Cced) in the discussion. I don't remember the details (and can't check right now) but there were discussions in linux-wireless mailing list. -- Kalle Valo-- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
