Hello All, I am using *VPP 19.04* version. As per my analysis icmp_responder application is receiving interrupts but memif_rx_burst API is always giving number of buffers as 0.
Below are logs collected on icmp_responder. root@balaji:~# ./icmp_responder INFO: tx qid: 0 LIBMEMIF EXAMPLE APP: ICMP_Responder ============================== libmemif version: 2.1 memif version: 512 use CTRL+C to exit MEMIF DETAILS ============================== interface name: memif_connection app name: ICMP_Responder remote interface name: remote app name: id: 0 secret: (null) role: slave mode: ethernet socket filename: /run/vpp/memif.sock socket filename: /run/vpp/memif.sock rx queues: tx queues: link: up INFO: memif connected! ICMP_Responder:on_interrupt:289: interrupted ICMP_Responder:on_interrupt:298: *received 0 buffers*. 0/256 alloc/free buffers ICMP_Responder:icmpr_buffer_alloc:237: allocated 0/0 buffers, 256 free buffers ICMP_Responder:on_interrupt:320: freed 0 buffers. 0/256 alloc/free buffers ICMP_Responder:icmpr_tx_burst:252: tx: 0/0 Do let me know if i am missing anything. Regards, Balaji
