This mail is a question mail more than patch mail.
In your commit "netdev: netdev_priv() can now be sane again.",
you said netdev_priv() != netdev->priv, because that time,
netdev->priv = ((char *)dev +((sizeof(struct net_device) +(sizeof(struct net_device_subqueue) *
(queue_count - 1)) + NETDEV_ALIGN_CONST) & ~NETDEV_ALIGN_CONST))
But now, after you do TX multiqueue improvement.
netdev->priv == netdev_priv() again.
That make me think, what the use of netdev->priv?
We have netdev_priv() and use it flexibly. Why don't kill netdev->priv?
