From 68e4e036b841d5fb23ae1ac51b1e40baf9d582bf Mon Sep 17 00:00:00 2001 From: James Ketrenos Date: Tue, 13 Sep 2005 17:37:22 -0500 Subject: [PATCH] [PATCH] Changed 802.11 headers to use ieee80211_info_element[0] Changed 802.11 headers to use ieee80211_info_element as zero sized array so that sizeof calculations do not account for IE sizes.
