why do you see it's being overwritten? How did you test that? two ifindex = two different netdev. And in case of e1k: struct e1000_adapter *adapter = netdev_priv(netdev); adapter->prog so we can have different programs on different netdevs even when they're both e1k, mlx or anything else. _______________________________________________ iovisor-dev mailing list [email protected] https://lists.iovisor.org/mailman/listinfo/iovisor-dev
