Subject: [PATCH] mac80211: Fix TKIP/WEP HT capability handling
Date: Mon, 2 Mar 2009 13:28:31 +0530 [thread overview]
Message-ID: <18859.37287.333376.924937@gargle.gargle.HOWL> (raw)
There is no need to parse the AP's HT capabilities if
the STA uses TKIP/WEP cipher. This allows the rate control
module to choose the correct(legacy) rate table.
