From 65e254821cee1a63f3f6d23270e90b33432b2bef Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 13 Apr 2016 14:24:22 +0200 Subject: iwlwifi: mvm: use firmware station PM notification for AP_LINK_PS When using RSS on 9000 series devices, we can't rely on processing the received frames for station powersave handling, since they could be processed on different CPUs and out of order. In order to still manage the powersave of stations, the firmware sends a notification on sleep->wake, wake->sleep and - for U-APSD - frames received with PM while already sleeping (with the TID.) With this, the driver can set AP_LINK_PS, which is required for real parallel RX. In addition, this requires checking for PS-Poll frames and calling ieee80211_sta_pspoll() appropriately.
