The following commit has been merged in the master branch: commit 351638e7deeed2ec8ce451b53d33921b3da68f83 Author: Jiri Pirko jiri@resnulli.us Date: Tue May 28 01:30:21 2013 +0000
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.
