From 2a901468c221e778af52603e006a53d286e81f90 Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 11 Nov 2013 22:15:31 +0100 Subject: [PATCH] cfg80211: add an option to disable processing country IEs Certain vendors may want to disable the processing of country IEs so that they can continue using the regulatory domain the driver or user has set. Currently there is no way to stop the core from processing country IEs, so add support to the core to ignore country IE hints.
