From 4dc15ca34591231e91a50b10320b6265e10aa127 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 10 Apr 2014 15:06:48 +0200 Subject: [PATCH] mac80211: exclude AP_VLAN interfaces from tx power calculation commit 764152ff66f4a8be1f9d7981e542ffdaa5bd7aff upstream. Their power value is initialized to zero. This patch fixes an issue where the configured power drops to the minimum value when AP_VLAN interfaces are created/removed.
