From 40b96408831f038b1a6b45e8b22cd050f82a3896 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 29 Sep 2011 16:04:38 +0200 Subject: mac80211: explicitly notify drivers of frame release iwlwifi needs to know the number of frames that are going to be sent to a station while it is asleep so it can properly handle the uCode blocking of that station. Before uAPSD, we got by by telling the device that a single frame was going to be released whenever we encountered IEEE80211_TX_CTL_POLL_RESPONSE. With uAPSD, however, that is no longer possible since there could be more than a single frame. To support this model, add a new callback to notify drivers when frames are going to be released.
