DHCPv6 packet crafting

It is easy to parse, create and manipulate DHCPv6 packets. The DHCPv6 interface is the central way to move packets around. Two concrete implementations, DHCPv6Message and DHCPv6Relay take care of the details. The example in main.go shows how to craft a DHCP6 Solicit message with a custom DUID_LLT, encapsulate it in a Relay message, and print its details.

The output (slightly modified for readability) is

$ go run main.go
2018/11/08 13:56:31 DHCPv6Relay
  messageType=RELAY-FORW
  hopcount=0
  linkaddr=2001:db8::1
  peeraddr=2001:db8::2
  options=[OptRelayMsg{relaymsg=DHCPv6Message(messageType=SOLICIT transactionID=0x9e0242, 4 options)}]
