Hi, To achieve line rate with a 400Gbs ConnectX-7 in my environment it appears MPRQ should be enabled.
With testpmd(DPDK 25.11) I observe ~line rate. I have a VPP 24.04 application (DPDK bumped to 25.11) but with MPRQ enabled most packet data is zeroed. Tracing shows the macs as 00:00:00:00:00:00 etc This looks to be a issue related to how VPP treats the data offset vs how DPDK treats the data offset in MPRQ mode. Has this been encountered by anyone ? , if so is there a patch / fix for this issue ? Has anyone achieved ~400Gbs on a ConnectX-7 with or without MPRQ enabled ? Gordon
