From d37d49c2f18fb53c6315b2b0fd7f1fb3d8be57ac Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Tue, 16 May 2017 11:23:11 +0200 Subject: wireless: Only join DFS channels in mesh mode if userspace flags support When joining a mesh network it is not guaranteed that userspace has a daemon listening for radar events. This is however required for channels requiring DFS. To flag that userspace will handle radar events, it needs to set NL80211_ATTR_HANDLE_DFS. This matches the current mechanism used for IBSS mode.
