From d2259243a19894eee06c16e278adfea81dc42bd9 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 20 Feb 2008 01:36:16 +0100 Subject: [PATCH] mac80211: invoke set_tim() callback after setting own TIM info Drivers should be allowed to simply get a complete new beacon when set_tim() is invoked (and set_tim() is required for drivers that just want a beacon template!), so we need to update our own TIM bitmap before calling set_tim() so that getting the beacon will now get an already updated beacon.
