Unable to delete DPDK DDP GTP Profile in Intel X710 NIC

Harrish · ‎09-27-2023

Hi Team,

I have configured DDP GTP Profile (gtp.pkg) downloaded from https://downloadcenter.intel.com/download/27587 and followed below steps:

testpmd> stop
testpmd> port stop 0
testpmd> ddp add 0 /usr/lib/firmware/intel/i40e/ddp/gtp.pkg

And the get list also retrieves the profile properly as below:

testpmd> ddp get list 0
Profile number is: 1

Profile 0:
Track id:     0x80000008
Version:      1.0.4.0
Profile name: GTPv1-C/U IPv4/IPv6 payload

Issue-1 : But when the packets are parsed using DPDK APIs the header fields are still classified as unknown.

Issue-2: We are unable to remove/delete the ddp profile configured and observing the below error

testpmd> ddp del 0 /usr/lib/firmware/intel/i40e/ddp/gtp.pkg
rte_pmd_i40e_process_ddp_package(): Failed to write profile for delete.
Failed to delete profile.
testpmd>

NIC Details:

dpdk-devbind.py -s

Could you please help us in resolving the issue with your inputs.?

Thanks in advance,
