From 1db364c88695272e3410eb4b5d4595c8cb15db30 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 17 Apr 2020 12:38:04 +0200 Subject: mac80211: mlme: remove duplicate AID bookkeeping Maintain the connection AID only in sdata->vif.bss_conf.aid, not also in sdata->u.mgd.aid. Keep setting that where we set ifmgd->aid before, which has the side effect of exposing the AID to the driver before the station entry (AP) is marked associated, in case it needs it then.
