From d9b3b28b93812715dcee8e4eed8cb8d0707a45f8 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Thu, 28 Jun 2012 15:03:13 +0300 Subject: [PATCH] mac80211: allow calling ieee80211_ap_probereq_get() during auth/assoc Drivers might need getting the probe request (e.g. in order to extract the ssid) even during auth/assoc. Make ieee80211_ap_probereq_get() support it by considering auth_data/assoc_data as well.
