Statically linked drivers can have netdev's that get unregistered and free'd up. For example we have a few cases where configuration calls allocate/register and deallocate/unregister net devices. I understand what you're trying to do, but I don't think this is the way to do it. I once thought we could play some games because of the invariant that if we have a route attached to the SKB, that holds an implicit reference for the netdevice too. But I know there are cases where the the route attached to the SKB is to a different device than the one that skb->dev is and should be set to. There is also a temptation to deal with this using per-cpu (or per-node) counters, and that's a too bloated solution. We should be making datastructures smaller not larger. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
