error: syscall.Bind SockaddrXDP failed: device or resource busy

[lddlww]

what's wrong with it?

i run with follow code: i want to create more xsk with same link, but it throw above error

func Newxsk(nic string, queue_id int) (*xdp.Socket, error) {
    fmt.Println(queue_id, nic)
    link, err := netlink.LinkByName(NIC)
    if err != nil {
        panic(err)
    }
    xsk, err := xdp.NewSocket(link.Attrs().Index, QueueID, nil)
    return xsk, err
}

var queueCount = 8

for i := 0; i < queueCount; i++ {
            xsk, err := Newxsk(NIC, i)
            if err != nil {
                panic(err)
            }
            xsks = append(xsks, xsk)
}
