Message-Id: <1369729460-28421-2-git-send-email-jiri@resnulli.us>
Date: Tue, 28 May 2013 10:24:18 +0200
From: Jiri Pirko <jiri@...nulli.us>
To: netdev@...r.kernel.org
Cc: davem@...emloft.net, eric.dumazet@...il.com, timo.teras@....fi,

Subject: [patch net-next v2 1/3] net: pass info struct via netdevice notifier
So far, only net_device * could be passed along with netdevice notifier
event. This patch provides a possibility to pass custom structure
able to provide info that event listener needs to know.
Signed-off-by: Jiri Pirko <jiri@...nulli.us>
v1->v2: fix notifier_call parameter in call_netdevice_notifier()
