From 8b60b07805d557542160d852874fa6a1b969184e Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Tue, 11 Oct 2011 10:59:02 -0700 Subject: cfg80211: process regulatory DFS region for countries The wireless-regdb now has support for mapping a country to one DFS region. CRDA sends this to us now so process it so we can provide that hint to drivers. This will later be used by code for processing DFS in a way that meets the criteria for the DFS region the country belongs to. Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.
