From 62da92fb75c346b503bca765fd1337e08771c9fe Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 19 Dec 2007 02:03:31 +0100 Subject: mac80211: support getting key sequence counters via cfg80211 This implements cfg80211's get_key() to allow retrieving the sequence counter for a TKIP or CCMP key from userspace. It also cleans up and documents the associated low-level driver interface. Signed-off-by: Johannes Berg Signed-off-by: John W. Linville Signed-off-by: David S.
