Hi all,
I have tried to run the pipeline example with a ROUTING pipeline where I
configured n_arp_entries=8 as well as the arp_key_offset = 192.
It compiles perfectly but when it reaches the line where the
rte_pipeline_table_create is (see below a fragment of the source code of
the pipeline_routi
Hi all,
I have realized that the PKT_TX_VLAN_PKT flag for Tx Vlan Offload doesn't
work in my application.
According to the NICs I have (IGB) there seems to be a problem with this
vlan offload tx feature and this version of DPDK according to the Bug 17 :
https://bugs.dpdk.org/show_bug.cgi?id=17
I
in the driver it will work, I
think.

Forget about it,
I found a bug in my software. Once solved, no problem with PKT_TX_VLAN_PKT
at all.

Bruce,
My requirements are not that much (500 Mbps and 1 Gbps desirable).
Thanks for your references links I will have a look at them.
Regarding the NIC detection in the DPDK app by the DPDK EAL initialization
after successfully having loaded the vfio-pci, it happens something strange.

Hi all,
I am trying to make an application for having various rx threads capturing
packets from various queues of the same NIC (to increase performance using
RSS on one NIC). I am basing the app on an example called l3fwd-thread.
However, when I try to create the rx queue in a port using the
rte_
I have found myself the solution to the problem.
When the struct rte_mempool *pktmbuf_pool[NB_SOCKETS]; was declared, it was
not initialized with NULL and the memory pool was not created because the
if clause 'if (pktmbuf_pool[socketID]==NULL)' avoided it.
Once I forced the initialization of all
Hi all,
In the project I am working I need to define custom metadata fields on each
packet once they are captured using DPDK.
I have seen that each packet has a headroom memory space (128 bytes long)
where RSS hashing and other metadata provided by the NIC is stored. This
information will be usefu
Thanks for your quick answer,
I have read so many documents and web pages on this issue that probably I
confounded the utility of the headroom. It is good to know that this 128
bytes space is available to my disposal. The fact of being lost once the
NIC transmits the frame it is not a problem at a

Hi all,
I am using DPDK development environment to develop an application from
which I have to access C++ code.
I managed to modify some internal mk files in the dpdk-stable repository to
allow g++ compiler to be supported.
I have all the modified files well identified and I wonder if the support

Hi all,
I am developing my own DPDK application basing it in the dpdk-stable
ip_pipeline example.
At this moment I am using the 17.11 LTS version of DPDK and I amb observing
some extrange behaviour. Maybe it is an old issue that can be solved
quickly so I would appreciate it if some expert can sha

Hi ,
I put some maintainers as destination that could provide some extra
information on this issue.
I hope they can shed some light on this.

Hi all,
the DPDK lib always crashes when a packet enters an ACL table I created to
check IPv6 fragmented packets. If the table is empty nothing happens as the
missed packets go to the next table in the pipeline but as soon as I put
some entries a crash happens when the first packet enters.

Hello,
I have exactly the same problem as you. I have also downloaded, compiled
and installed the very last version of valgrind (v3.17).
As soon as the mempool is created, the program gets stuck.
If valgrind cannot be used with DPDK (I am using v18.11.5) as memory leak
debugger, there must be oth
