From 6d9d32b89ab0f9cbd182f807cc484e66e15c6972 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 6 Aug 2013 18:58:56 +0200 Subject: iwlwifi: mvm: keep connection to AP after WoWLAN Until now, after WoWLAN, we weren't able to keep the connection to the AP because the firmware didn't give us the right information. Since the firmware API has been changed to include all the information we need, change the driver to work with the new API (if it is available) and program all the relevant information in mac80211 to keep the connection.
