From 9b7a0ddc6073909bc61399ca3b8126ef886d5e8a Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Sun, 25 Jan 2015 20:31:33 +0100 Subject: [PATCH] brcmfmac: pass DEAUTH/DISASSOC reason code to user-space The driver always called cfg80211_disconnected() with reason parameter set to zero, ie. unknown. However, firmware does provide a valid 802.11 reason code in DEAUTH and DISASSOC event message to the driver. This patch passes the reason code to cfg80211_disconnected().
