From a30d50b324bc50f27a341016faeb4949afdedaff Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Mon, 18 Nov 2013 17:57:07 +0200 Subject: [PATCH] P2P: Prefer HT40 channels for initial pick If there are no other preferences from local configuration or driver, prefer a random HT40 channel instead of falling back to the fixed pre-configured channel or 5 GHz channel preference.
