From 131a19bc924c32cecd014be7036686f2186b48ad Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 4 Mar 2013 20:54:46 +0100 Subject: [PATCH] regulatory: enable channels 52-64 and 100-144 for world roaming If allowed in a country, these channels typically require DFS so mark them as such. Channel 144 is a bit special, it's coming into use now to allow more VHT 80 channels, but world roaming with passive scanning is acceptable anyway. It seems fairly unlikely that it'll be used as the control channel for a VHT AP, but it needs to be present to allow a full VHT connection to an AP that uses it as one of the secondary channels. Also enable VHT 160 on these channels, and also for channels 36-48 to be able to use VHT 160 there.
