Hello Asaf,
We generate incoming IPinIP packets by using our complex solution, but belo=
w you can find a Python script to generate such packets to serve this purpo=
se. I hope it is helpful to reproduce this issue. Thanks again.
<Code snippet to generate IPinIP packets>
#!/usr/bin/python3
from scapy.all import *
from scapy.layers.inet import Ether, UDP, ICMP
from scapy.layers.inet6 import *
ether =3D Ether()
ether.src =3D "src mac"
ether.dst =3D "dst mac"
ether.type =3D 0x86DD
ipv6 =3D IPv6()
ipv6.src =3D "src ipv6 addr"
ipv6.dst =3D "dst ipv6 addr"
ipv6.nh =3D 4
pkt =3D ether / ipv6 / IP(src=3D"192.168.129.5",dst=3D"172.32.4.9") / ICMP(=

print(pkt.show())

Subject: Re: Finer matching granularity with async template API
Hellp Asaf,
Thanks for your speedy reply. Please find additional information based on y=
our questions, and I hope they would help to understand our purpose and iss=
ue.
1. Why ipv6/ipv4/icmp?
We are performing IPinIP tunnelling for traffic, and in this provided test-=
pmd example we encapsulate IPv4 packets from VMs into IPv6 underlay packets=
. The refence RFCs for this approach are RFC 1853 and RFC 2473. This articl=
e<https://www.h3c.com/en/Support/Resource_Center/HK/Switches/H3C_S7500E_X/S=
7500E-X/Technical_Documents/Configure___Deploy/Configuration_Guides/H3C_S75=
00E-X_CG-Release7178-6W100/05/201602/914694_294551_0.htm> also provides goo=
d visualization on packet structures for this IPinIP tunnelling approach.
1. What output /error message?
No crashing error message or similar happens, thus it is difficult for us t=
o debug what is exactly going on. What is observed is that incoming packets=
cannot be captured and processed by this flow rule, compared with using t=
he flow rule only performs eth/ipv6 matching. After removing relevant comma=
nds or code that perform inner header matching for IPv4 and ICMP, packets c=
an be successfully processed. The code snippets to programmably achieve the=
above described IPinIP tunnelling approach are as following:

Once I remove matching patterns for the inner packet headers( ipv4 / icmp) =
as following, I can see the processed packets inside VMs using tcpdump.

Similar combination works when using the synchronous rte_flow API. Any comm=
ent or suggestion on this issue is much appreciated. Many thanks in advance=
