Hi
I am interested to do ipsec encoding and decoding in my dpdk application
From my readings, i understand ipsec can be done one time in the nic (inline
ipsec) or with multiple calls (rte_cryptodev_enqueue_burst,
rte_cryptodev_dequeue_burst)
1. If ipsec is done by nic I only need to cal
I have 2 pods running on same worker
Pod1 send to pod2
Pod2 receive with 4 bytes less at end of packet
This problem happens only if the 2 nic are on the same pf,
If different pf, the problem doesn’t occurs
I tried with dpdk21 and dpdk22
The code is using driver net_iavf
nic e810c
driver: ice

I am using Mellanox Technologies MT27800 Family [ConnectX-5], using dpdk 19
with multi rx queue with rss port_conf.rx_adv_conf.rss_conf.rss_hf=(ETH_RSS_IP

Hi
I am using multiqueue with RSS to read from MT27800 Family [ConnectX-5] 1017
My application receive traffic, and write some data to disk. As a result I/O
write is cached in linux memory.
When the server memory is completely cache ( I know it is still available) I
start seeing drops at nic.

I moved from dpdk 19 to dpdk 21
I read with multiqueue from Mellanox 100G card with dpdk function
rte_eth_rx_burst
I can see in perf top very high cpu on function rxq_cq_process_v
How can i fix it? This function wasn't in my perf top with dpdk 19 version

Hi
We try to read from 100G NIC Mellanox ConnectX-5 without drop at nic.
All thread are with core pinning and cpu isolation.
We use dpdk 19.11
I tried to apply all configuration that are in
https://fast.dpdk.org/doc/perf/DPDK_19_08_Mellanox_NIC_performance_report.pdf
We have a strange behavior,
ill get non-hot mbufs to work with.
It can be one of the reasons for the earlier drops you see.

I am using mellanox Connectx6, dpdk 22
'MT2892 Family [ConnectX-6 Dx] 101d' if=ens5f1 drv=mlx5_core unused=igb_uio
I configure port with multiqueue and split traffic according to ip+port
I want to calculate the hash as the nic do, to be able to load balance traffic
( from another card ) - the info
nother instance
How can I solve this?

Hi
Is this possible to use dpdk rte rss flow with a vf sriov, or is it an option
available only for real interface?
I use dpdk 19.11 and a Mellanox card 100G with mlx5
am not asking about the RTE_FLOW_ACTION_TYPE_VF – When you said
Mellanox support where you referring to RTE_FLOW_ACTION_TYPE_VF?

Hi
I want to give an ip to a dpdk port, because I need to receive traffic
by gre replication.
I though I could do it with dpdk kni
(http://dpdk.org/doc/guides/prog_guide/kernel_nic_interface.html)
I am able to give an ip to interface vEth0, but I can't ping or ssh to
the ip address.
I set
The source of my problem seems to be that Ethtool is not supported in
VMs (VF).
Is there another solution to give an ip to a dpdk port?
