Because dpdk only takes over one network card, I comm= ented out the parameter restrictions in argc.c under mp_server. The mp_serv= er service is started successfully. Procedure No data is displayed when a p= acket is sent through a network cable. Procedure But there is data with dpd= k-testpmd. I have not encountered such a problem before and hope to get hel= p. Which network interface are you using? Some network drivers are broken in t= he Multi-process mode. Are there any log messages on startup?
