From 20d2ebe512b9ad0f8fdd867a02d7a309344e8a6a Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Sun, 15 Jul 2012 23:44:58 +0100 Subject: libertas: Update 11d info only when interface is active reg_notifier can be called before the interface is up. Handle this correctly by storing the requested country code, then apply the relevant configuration when the interface is brought up.
