I use the dpdk-23-11 version, system debian11, network card i210, CPU Cortex-A55. After the dpdk-23-11 service is compiled and installed, Start dpdk-23-11/examples/multi-process/cron_derve_mp/mp_derver/ build/mpuserver -l 1-2 -n 4 -- -p 1- n 1. Because dpdk only takes over one network card, I commented out the parameter restrictions in argc.c under mp_server. The mp_server service is started successfully. Procedure No data is displayed when a packet is sent through a network cable. Procedure But there is data with dpdk-testpmd. I have not encountered such a problem before and hope to get help.

Which network interface are you using? Some network drivers are broken in the Multi-process mode.
Are there any log messages on startup?
