for nic which has multi queues, it would be more index associate with one nic； i want to create different links using "eth0", but follow code always get same Index

link, err := netlink.LinkByName("eth0")
fmt.Println(link.Attrs().Index) // output: 2

link, err := netlink.LinkByName("eth0")
fmt.Println(link.Attrs().Index)// output: 2

how can i do ?

This is not possible in Linux' current model. Queues are aggregated into netdevs to the best of my knowledge, and there isn't any virtual netdev kind that would allow extracting queues into new netdevs, not least as this would need removing queues, IRQ nightmares, and many follow-up problems.
