Module: PacketFu::IPv6HeaderMixin

Included in:
ICMPv6Packet, IPv6Packet, TCPPacket, UDPPacket
Defined in:
lib/packetfu/protos/ipv6/mixin.rb

Overview

This Mixin simplifies access to the IPv6Headers. Mix this in with your packet interface, and it will add methods that essentially delegate to the ‘ipv6_header’ method (assuming that it is a IPv6Header object)
