From cca89496a8afe4ad12ce1e468e60cef1e27e4eee Mon Sep 17 00:00:00 2001 From: Javier Cardona Date: Mon, 10 Aug 2009 17:29:29 -0700 Subject: [PATCH] mac80211: Fix unresolved mesh frames queued without valid control.vif Mesh frames that could not be immediately resolved were queued with a NULL info->control.vif. This patch moves the call to mesh_nexthop_lookup closer to the point where it is handed over to ieee80211_tx(). This ensures that the unresolved frames are ready to be sent once the path is resolved.
