From 265dc7f0964e4df95ab57a9d1618689301d39a55 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Fri, 4 Dec 2009 19:10:34 +0200 Subject: [PATCH] mac80211_hwsim: Check all local addresses for TX Ack status Since mac80211_hwsim supports multiple virtual interfaces, we need to iterate through all active interfaces when figuring out whether there is a match during TX Ack status checking. This fixes TX status reporting for cases where secondary interfaces are used. Signed-off-by: Jouni Malinen Signed-off-by: John W.
