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

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
nother instance
How can I solve this?

Hi
Is there a way using rte_flow to send arp and ndp packet to specific rx queue

I moved from dpdk 19 to dpdk 21

I am using multiqueue with RSS to read from MT27800 Family [ConnectX-5] 1017

I analyze traffic and need all packet of same session to arrive to the same

ill get non-hot mbufs to work with.
It can be one of the reasons for the earlier drops you see.

Hi
I am using the dpdk igb_uio in vm instead of ixgbevf
To get the mac address from code I call function rte_eth_macaddr_get
How do I get the vlan id assigned to the vf I am using, is there a similar
function?
So I can't know if there where dropps!!!
Is this the same for dpdk with virtio? Can I know if there where dropps?

Hi
There is no statistics of missed packet for ixgbevf in a vm.
How can I get these stats?
In ixgbe it is called imissed
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?
