From 88a93df4cbc1342108356bda4f163d5cb78b6381 Mon Sep 17 00:00:00 2001 From: Zhu Yi Date: Mon, 21 Aug 2006 11:38:08 +0800 Subject: [PATCH] [PATCH] ipw2200: remove the MAC timestamp present field from radiotap head IEEE80211_RADIOTAP_TSFT is defined as the Value in microseconds of the MAC's 64-bit 802.11 Time Synchronization Function timer when the first bit of the MPDU arrived at the MAC. Since ipw2200 hardware doesn't provide this value, we disable this feature from the radiotap header present flag. Signed-off-by: Zhu Yi Signed-off-by: John W.
