From 51da3d8b94485a8397ae7af3bfdb65feaf582202 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 12 Jun 2017 11:24:06 +0200 Subject: [PATCH] iwlwifi: mvm: quietly accept non-sta disassoc frames Git-commit: 51da3d8b94485a8397ae7af3bfdb65feaf582202 Patch-mainline: v4.13-rc1 References: bsc#1051510 When a station that's not associated sends a data frame (e.g. an NDP) hostapd will respond with a disassoc frame, telling it that it's not associated. The station might also not be authenticated, in which case there will not be a station entry for it, and as a result we need to accept such frames without a station.
