From 64e29e447ec01d2130b4c68f3459cfaa94fa138b Mon Sep 17 00:00:00 2001 From: Teemu Paasikivi Date: Fri, 26 Mar 2010 12:53:26 +0200 Subject: [PATCH] wl1271: Removed checking of PSM from handling BSS_LOST_EVENT Change the driver to call ieee80211_beacon_loss function always when BSS_LOST_EVENT is received. Reason for the change is that entering PSM might fail before driver receives BSS_LOST_EVENT. In such case the driver would disable PSM and the stack would not be notified about beacon loss and connection loss detection would be delayed by tens of seconds.
