From 1c0bbecc26637b7cdd4f7aad19b9141a6524678e 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.
