From e189277a3f1cbb0f1282e0f4b8fa8c91e004c286 Mon Sep 17 00:00:00 2001 From: Volker Braun Date: Mon, 24 Oct 2005 10:15:36 -0500 Subject: Fix problem with WEP unicast key > index 0 The functions ieee80211_wx_{get,set}_encodeext fail if one tries to set unicast (IW_ENCODE_EXT_GROUP_KEY not set) keys at key indices>0. But at least some Cisco APs dish out dynamic WEP unicast keys at index !=0.
