Detailed Description

hICN packet format type

The hICN type represents the sequence of protocols that we can find in packet headers. They are represented as a quartet of u8 values, correponding to IANA protocol assignment, and read from right to left. This is done to faciliate decapsulation of packet header by simple shift/mask operations.

For instance, an IPv6/TCP packet will be identified as : [IPPROTO_NONE, IPPROTO_NONE, IPPROTO_TCP, IPPROTO_IPV6]

We expect four elements to be sufficient for most uses, the max being currently used by an hypothetical signed MAP-Me update : [IPPROTO_ICMPRD, IPPROTO_AH, IPPROTO_ICMP, IPPROTO_IPV6]
