From b4d57adb727ec7c34020390eeb0eeb9e0a2959bc Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 31 Jan 2010 23:25:24 +0100 Subject: [PATCH] mac80211: fix sta lookup with AP VLAN interfaces and injected frames When injecting frames, mac80211 currently looks for the first AP interface that matches the source address of the injected frame. This breaks when such a frame is directed at a STA that has been moved to a VLAN. This patch fixes it by using sta_info_get_bss instead of sta_info_get, which also finds stations belonging to a VLAN interface of the same BSS as the AP interface.
