From 3549716484a95fd16f7fcf8b68699bd4c803b382 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Mon, 15 Jun 2009 21:59:54 +0200 Subject: iwmc3200wifi: cache keys when interface is down When the interface is down and one sets a WEP key from userspace, we should be able to simply cache it. Since that implies setting part of the profile's security settings, we now alloc/free the umac_profile at probe/remove time, and no longer at interface bring up/down time. Simply resetting it during the latter is enough. Signed-off-by: Samuel Ortiz Signed-off-by: John W.
