Hi, Something is still creating the problem. just can't figure out.
Here is the scenario.... Just inserted IGB UIO module, attached one 10G NIC to DPDK & 4096 hugepage. --- trying to run l3fwd as primary and pducp as secondary to capture packet dump. Earlier dpdk_pdump is crashing on either create_mp_ring_vdev:649 or create_mp_ring_vdev:669. Now i changed some parameters of pdump and l3fwd, change hugepages to 8192 and tried to run like this.. *./l3fwd -c 606 -n 4 --proc-type=primary --socket-mem=1024 --file-prefix l3f -- -p 0x1 --config="(0,0,1),(0,1,2)"* Here is the log of app " EAL: Detected 16 lcore(s) EAL: Probing VFIO support... EAL: VFIO support initialized PMD: bnxt_rte_pmd_init() called for (null) EAL: PCI device 0000:03:00.0 on NUMA socket 0 EAL: probe driver: 8086:15ad rte_ixgbe_pmd EAL: PCI device 0000:03:00.1 on NUMA socket 0 EAL: probe driver: 8086:15ad rte_ixgbe_pmd EAL: PCI device 0000:05:00.0 on NUMA socket 0 EAL: probe driver: 8086:1521 rte_igb_pmd EAL: PCI device 0000:05:00.1 on NUMA socket 0 EAL: probe driver: 8086:1521 rte_igb_pmd L3FWD: LPM or EM none selected, default LPM on Initializing port 0 ...

So I tried to run pdump like * ./dpdk_pdump -- --pdump 'port=0,queue=*,rx-dev=/tmp/rx-file.pcap,tx-dev=/tmp/tx-file.pcap,ring-size=1024,mbuf-size=20,total-num-mbufs=1025'* Here is log for pdump " EAL: Detected 16 lcore(s) EAL: Probing VFIO support...
