Just to update, root cause is found...
the problem is not at the dpdk rx side but at the transmit side (using
sendto app).
when transmitting through NICs models 82575 or 82576 (sendto app), the
receiver reads it well using the DPDK rx program.
however when using NIC 82541gi as transmitter (sendto
The CONFIG_RTE_LIBRTE_MEMPOOL_DEBUG and CONFIG_RTE_LIBRTE_MBUF_DEBUG didn't
provide any input, so I also added the CONFIG_RTE_LIBRTE_ETHDEV_DEBUG and
CONFIG_RTE_LIBRTE_IGB_PMD.
below is a sample log showing the problem, though I don't see any clue in
the logs.
in this case pkt 58509 is placed at t
I will try it though I hope the amount of logs won't affect the result.
while analyzing the wireshark captures I noted that the packet i supposed
to capture arrives in a short time after the one before.
for example, here is a time between the consecutive transmitted packets:
0.5 PKT 12201

Hi,
I still can't get over this issue and need some help here.
in order to investigate this issue i wrote a very simple app that do:
rte_eth_rx_burst(port[i].portid, 0, pkts_burst, MAX_PKT_BURST)
printf the udp pkt content
rte_pktmbuf_free(pkts_burst[j]);
on my host i wro
Hi All,
I face a very strange behavior.
I do:
rte_eth_rx_burst(port[i].portid, 0, pkts_burst, MAX_PKT_BURST)
then I reassemble the received UDP segments into one packet (i used the
ip_reassembly example), manipulate its content and send it back to the
network after fragmenting the packet.
