From c9b22fb87a00ceb8afa78089d5cf676cf8b3319d Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Mon, 25 Jun 2012 10:48:25 +0300 Subject: mac80211: don't require associated->beacon_ies for ps beacon_ies is needed only in order to extract the dtim period. However, even if it's missing we can still enter ps with dtim=1 (which also happens if the TIM ie is invalid). Most drivers don't use conf.max_sleep_period/ps_dtim_period anyway, and this check prevents them from entering ps if they don't have beacon (but only probe response), even though the beacon is not needed at all.
