From 8d6f658e211a3c6ff808f7fc6ebb30239457eabc Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Mon, 15 Dec 2008 10:37:50 +0200 Subject: [PATCH] mac80211: Remove radiotap rate-present flag for HT Since we do not currently report HT rates (MCS index) in radiotap header for HT rates, we should not claim the rate is present. The rate octet itself is used as padding in this case, so only the it_present flag needs to be removed in case of HT rates. Signed-off-by: Jouni Malinen Signed-off-by: John W.
