From 76b817f6c9a901c4d1e7b9e4e4c7b69ce8330353 Mon Sep 17 00:00:00 2001 From: Pierre Le Magourou Date: Mon, 18 Jul 2016 23:22:20 +0300 Subject: [PATCH] ath6kl: Unset IFF_LOWER_UP flag on AP mode leave. When disabling tethering after having enabled it, the ath6kl driver does not set the IFF_LOWER_UP flag to 0 (carrier off) on the wlan interface. The upper layers (eg. connman) are not notified of the tethering mode status change. So, tethering can not be activated anymore. This patch adds a netif_carrier_off() call when stopping AP mode to fix the problem.
