[PATCH dpdk] net: add more icmp types and code

[Robin Jarry]

Add more ICMP message types and codes based on RFC 792. Change the
namespace prefix from RTE_IP_ICMP_ to RTE_ICMP_ to allow differentiation
between types and codes.

+1 to get this in 24.11

@Thomas, probably it is better to get this for -rc1 and as next-net
already pulled can this directly go to main?


Btw, is following also required? Just because it is documented in RFC:
   15  Information Request
   16  Information Reply

Ack stands if above added or not.

I will probably send a v2 with a release note.

It seems some of the original codes have been deprecated:

[PATCH dpdk v2] net: add more icmp types and code

[Robin Jarry]

Add more ICMP message types and codes based on RFC 792. Change the
namespace prefix from RTE_IP_ICMP_ to RTE_ICMP_ to allow differentiation
between types and codes.

Do not include deprecated message types as described in RFC 6918.
