From: Teemu Paasikivi Date: Fri, 26 Mar 2010 10:53:26 +0000 (+0200) Subject: wl1271: Removed checking of PSM from handling BSS_LOST_EVENT X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=64e29e447ec01d2130b4c68f3459cfaa94fa138b;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git 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.
