Hi, > Yes, or alternatively add an optional alloc_netdev() rtnl ops, e.g. in > rtnl_create_link: Yes, that works. It needs some more fiddling (we need 'data', not just 'tb') and it cannot be called 'alloc_netdev' (that's a macro!), but yeah, otherwise works. I'll just call it alloc(). I'll send a few updated patches in a few minutes. johannes
