I want to know 2 things a)the difference of dpdk-pdump between 21.08 and 21.11 (seems bpf changes)= =20 b)where pcap capture the ring buffer for secondary process? The output is coming from print_pdump_stats function is zero for 3 paramete= rs.(N.B.1)=20 Above parameters are counted on pdump_rxtx function.(it is zero on this fun= ction also)=20 The ring seems copied under mp_handle (process_msg) or mp_pdump. P.S. I understand dpdk-pdump seems to be deprecated by introducing dpdk-dumpcap.
