From 9184d9348a7a0e60d70d5f4c23de79fdbc72b9a3 Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Thu, 19 Jan 2006 16:22:32 +0800 Subject: [PATCH] ieee80211: Add TKIP crypt->build_iv This patch adds ieee80211 TKIP build_iv() method to support hardwares that can do TKIP encryption but relies on ieee80211 layer to build the IV. It also changes the build_iv() interface to return the key if possible after the IV is built (this is required by TKIP). Signed-off-by: Zhu Yi Signed-off-by: John W.
