- I am developing in the following environment, but I encountered an issue with RSS and cannot proceed any further.
Environment: OS Ubuntu Ubuntu 24.04.2 LTS (6.8.0-63-generic), DPDK stable-24.11.2, Intel X710 (version: 6.8.0-63-generic, firmware-version: 6.01 0x800035b1 1.1876. , DDP (v1.0.4.0)
I referred to the following document (supported DDP in GTP) and tried to configure GTP for RSS in DPDK, but it outputs a message saying it is not supported.
Is there any way to resolve this issue?

Hi Amina
Please let me know what additional details are needed besides the OS (kernel version), Intel X710 driver and firmware version, and the DDP version.
I will check and provide them.

Hello jung1,
Good day!
Kindly provide us the below details so that we can check this further for you.
1) The system/server model details in which this ethernet adapter is present ( model name)
2) The complete model name of this X710 adapter
3) Is it a built-in adapter or was it manually added later?
4) Would you be able to share a screenshot of the error message that you are getting?

Hello. Ragulan.
I performed the NVM update and ran the test using the method you provided.
However, I was unable to update the X710 using the latest NVM version 9.54.
So I proceeded with the update using version 9.50 instead.
# ethtool -i ens786f1np1
driver: i40e
version: 6.8.0-64-generic
firmware-version: 9.50 0x8000f4fb 1.3682.0

bus-info: 0000:2a:00.1
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes
After that, I ran the tests again, but DPDK still outputs the same message,
indicating that "#define RTE_ETH_RSS_GTPU RTE_BIT64(23)" is not supported.

Hello Jung1,
Thank you for the feedback.
As outlined in the Intel Ethernet 700 Series GTPv1 Profile Application Note, GTP-U RSS is not enabled by default. However, it can be supported by applying a Dynamic Device Personalization (DDP) profile designed specifically for GTPv1.
Without the DDP profile, the NIC is unable to parse GTP-U headers. This means that features like RSS or flow director won’t function on GTP-encapsulated traffic, as the NIC sees the GTP payload as generic UDP.
Applying the GTPv1 DDP profile allows the NIC to:
- Parse GTP headers
- Use TEID and inner IP addresses for RSS hashing
- Distribute GTP-U traffic across multiple queues using RSS
Requirements:
- Intel Ethernet 700 Series NIC (e.g., X710)
- Firmware version 6.01 or newer
- DPDK version 17.11 or later (your 24.11.2 version is fully supported)
- GTPv1 DDP profile (gtp.pkgo) loaded via DPDK tools or API
Important Note:
The DDP profile must be explicitly applied using DPDK. Without this, you will continue to see the “not supported” message when enabling GTP RSS.
Recommended Actions:
- Load the gtp.pkgo DDP profile onto the NIC using DPDK
- Confirm your firmware is up to date (v6.01+)
- Map the relevant PCTYPEs (e.g., GTPU IPV4) to DPDK flow types to enable RSS
We hope this clarifies your concerns. If there are any further queries, do let us know and we will be happy to assist.

Hello. Ragulan_Intel
understand what you are saying.
However, the DDP profile is not functioning properly.
I have tried both the gtp.pkgo file and the gtp-ext.pkgo file, but the RSS configuration itself doesn't work.
As I mentioned in the post, all the requirements are satisfied.
For example: Intel X710, firmware 9.50, DPDK 24.04.2 LTS, gtp.pkgo (v1.0.4.0), etc.
Please read my post carefully and respond accordingly.
This is getting really frustrating.
