Hi all,
I just started to use dpdk-pdump and got some problem with it. Appreciate
your help!
By following the document, I got testpmd running with pdump framework
initialized and tried to start dpdk-pdump as a secondary process. However,
I failed to start dpdk-pdump.
My testpmd was running like:
ixgbe_recv_scattered_pkts was set to be the rx function. Receiving packets
smaller than mbuf size works perfectly. However, if an incoming packet is
greater than the maximum acceptable length of one ?mbuf? data size,
receiving does not work. In this case, isn't it supposed to use
mbuf chaining to r
Any pointers to what the issue could be? thanks

Hello,
I am trying to use multi-segment mbuf to receive large packet. I enabled
jumbo_frame and enable_scatter for the port and was expecting mbuf chaining
would be used to receive packets larger than the mbuf size (which was set
to 2048).

I am trying multi-segment mbuf, but it seems not working.
On my target host, the mbuf size is set to 2048 and I am trying to send
large packet to it (say 2500 bytes without fragmentation) from another
host. I enabled both jumbo_frame and enable_scatter for the port. But I saw

Played with it a little bit more. It can receive packets only if
promiscuous mode is enabled in DPDK.

I am running DPDK application (testpmd) within a VM based on virtio. With
the same hypervisor and same DPDK code, it used to work well. But it
stopped working since last week. The VM's port could not receive anything.
I ran tcpdump on host's physical port, bridge interface as well as vnet
interface

I am running dpdk within a virtual guest as a L3 forwarder.
The VM has two ports connecting to two linux bridges (in turn connecting
two physical ports). DPDK is used to forward between these two ports (one
port connected to traffic generator and the other connected to sink). I
used iperf to test
I am running dpdk in KVM-based virtual machine. Two ports were bound to
igb_uio driver and KNI generated two ports vEth0 and vEth1. I was trying to
use ethtool to get information of these two ports, but failed to do so. It
reported "Operation not supported".
How to address this issue?
Thanks

I am running dpdk with a virtual guest as a L2 forwarder.
If the virtual guest is on passthrough, dpdk can achieve around 10G
throughput. However if the virtual guest is on virtio, dpdk achieves just
150M throughput, which is a huge degrade. Any idea what could be the cause
