From 7ffbe3fdace0bdfcdab8dc6c77506feda0871f79 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 2 Oct 2009 05:15:27 +0000 Subject: [PATCH] net: introduce NETDEV_POST_INIT notifier For various purposes including a wireless extensions bugfix, we need to hook into the netdev creation before before netdev_register_kobject(). This will also ease doing the dev type assignment that Marcel was working on for cfg80211 drivers w/o touching them all.
