How to send icmpv6NS packets through gopacket

```go
ethernetLayer := &layers.Ethernet{
SrcMAC: srcMac,
DstMAC: dstMac,
EthernetType: layers.EthernetTypeIPv6,
}

ipv6layers := &layers.IPv6{
Version: 6,
SrcIP: srcIP,
DstIP: snm,
NextHeader: layers.IPProtocolICMPv6,

}

icmplayers := &layers.ICMPv6NeighborSolicitation{
TargetAddress: srcIP,

}

buffer := gopacket.NewSerializeBuffer()
opts := gopacket.SerializeOptions{
FixLengths: true,
ComputeChecksums: true,
}
err := gopacket.SerializeLayers(buffer, opts,
ethernetLayer,
ipv6layers,
icmplayers,
)
```

Through the above construction of data packet transmission, it is found that the data packet is defective in wireshark capture.

Is there something wrong with the icmp-layers construction?
