From a073d13baad8715680c3cc216f57cde7ddc786f4 Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Thu, 5 Jun 2014 14:55:10 +0000 Subject: [PATCH] wpa_supplicant: fix locking hostapd to 20MHz (#12720) Fixed wpa_supplicant when the radio is in 40MHz mode so that it no longer restarts hostapd with the second channel disabled.
