From: Sara Sharon Date: Tue, 2 Feb 2016 09:55:53 +0000 (+0200) Subject: iwlwifi: mvm: extend time event duration X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7c70fee5ae5c4fb542e432599cb85c8031b952a0;p=linux-beck.git iwlwifi: mvm: extend time event duration Before authentication, we start a time event during which we wait for a beacon in order to sync our timers. If we didn't hear the beacon during this time - we abandon the connection. However, in congested environment, it was observed we might not hear beacons in that time slot. Extend the time event to give the connection a better chance.
