From cd36c0d2f093ec6b8a2c6e9b7b300a2fd4fc87b3 Mon Sep 17 00:00:00 2001 From: Davide Fioravanti Date: Thu, 17 Sep 2020 15:40:27 +0200 Subject: [PATCH] mac80211: select the first available channel for 5GHz interfaces Some 5GHz wifi interfaces, especially in Tri-band routers, can't use channel 36. In these cases, the default configuration for 5GHz interfaces, once enabled, doesn't work. This patch selects the first non-disabled channel for 5GHz interfaces.
