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. OK, becasue Dave S. Miller said, "every direct netdev->priv usage is a bug", and I want to kill netdev->priv later, I decided to convert all the direct reference of netdev->priv first. Different to readonly reference of netdev->priv, in this driver, netdev->priv was changed. I use netdev->ml_priv to replace netdev->priv. Signed-off-by: Wang Chen <redacted>
Thank you for your patch. However, I do not understand why you didn't simply replace netdev->priv with netdev_priv()? Can you explain? Thanks, John -- John W. Linville linville@tuxdriver.com
