Hi everyone, I’m seeing a packet length issue after upgrading to *VPP 25.02* on *ARM64 (Ampere® Altra® Q64-30 @ 3.0GHz)* with an *Intel E810-C (4x ports)* NIC using the *IAVF driver*.
All packets received in the *dpdk-input node* show a *length of 65535 bytes*, which is clearly incorrect. This is visible in both *trace* and *pcap* captures. Here’s what I’ve observed so far: - The issue only appears with *VPP 25.02* on *ARM64*. - The *same platform (hardware + NIC)* works perfectly with *VPP 22.02* — packet lengths are reported correctly. - On *X86 *systems, *VPP 25.02* also works fine (no packet length issue). - So it seems specific to *VPP 25.02 + ARM64 + IAVF driver* combination. *Setup details:* - *CPU:* Ampere® Altra® Q64-30 (ARM64) - *NIC:* Intel E810-C (4 ports) - *Driver:* IAVF (DPDK) - *VPP version:* 25.02 - *Symptom:* All packets show length = 65535 in dpdk-input node Has anyone else seen this behavior or is aware of any related changes in *VPP 25.02* or the *IAVF/DPDK layer* for ARM64? Would appreciate any pointers, patches, or debug hints — especially if someone has tested E810/IAVF on ARM with newer VPP versions. Thanks a lot in advance! *Nousi.*
