From e7a64f12a452d39ab50e5580e93bc48b3b15f30c Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 28 Aug 2007 17:01:55 -0400 Subject: [PATCH] [MAC80211]: add interface index to key debugfs Add a new file 'ifindex' to each key's debugfs dir to allow finding which interface the key was configured on. This isn't done as a symlink because of possible netdev name changes. Signed-off-by: Johannes Berg Acked-by: Michael Wu Signed-off-by: John W. Linville Signed-off-by: David S.
