From 454d7c9b14e20fd1949e2686e9de4a2926e01476 Mon Sep 17 00:00:00 2001 From: Wang Chen Date: Wed, 12 Nov 2008 23:37:49 -0800 Subject: netdevice: safe convert to netdev_priv() #part-1 We have some reasons to kill netdev->priv: 1. netdev->priv is equal to netdev_priv(). 2. netdev_priv() wraps the calculation of netdev->priv's offset, obviously netdev_priv() is more flexible than netdev->priv. But we cann't kill netdev->priv, because so many drivers reference to it directly. This patch is a safe convert for netdev->priv to netdev_priv(netdev). Since all of the netdev->priv is only for read. But it is too big to be sent in one mail. I split it to 4 parts and make every part smaller than 100,000 bytes, which is max size allowed by vger.
