From 8be30c13ebafdf743ab638a83095715a01bc1071 Mon Sep 17 00:00:00 2001 From: Ayala Beker Date: Wed, 16 Dec 2015 00:32:07 +0200 Subject: [PATCH] iwlwifi: mvm: Change number of associated stations when station becomes associated Currently, the number of associated stations gets updated when adding a new station or removing it. This is incorrect as it's possible that a station was inserted before it was associated Fix this by increasing/decreasing ap_assoc_sta_count whenever a station transitions in/out the associated state.
