Running one directional traffic from Spirent traffic generator to l2fwd
running inside a guest OS on a RHEL 6.2 KVM host, I encountered performance
issue and need to increase the number of rxd and txd from 256 to 1024.
There was not enough freeslots for packets to be transmitted in this routine
Hello,
I'm having trouble using l2fwd example on top of KVM guest with sr-iov. Here
goes the detailed description:
Symptoms:
If I run l2fwd dpdk-app, this app does not receive any packets. Even worse,
pass-thru-ed device in KVM guest is not receiving any interrupts and more
over,
PF in host

Hi,
I have a question about how to know corresponding device from port number.
For example, if I have 4 Ethernet devices and 2 Ring PMDs, I will get 6
ports during initialization.
In the case, how can I know which port corresponds last Ring PMD?

The process is to send your patch with git (format-patch + send-email).
You have to set a short title and a longer commit log explaining what was the
problem and how you fix
The mbufs returned by the pcap pmd RX function were constantly
reused, instead of being allocated on demand. This has been fixed.

I have a Ubuntu 12.04.3 LTS (Linux 3.2.0-53-generic) KVM host. The guest OS
is a CentOS 32bit (CentOS 6.2, Linux 2.6.32-220.el6.i686). There are two
10G ports on the KVM host with the following kvm.

I have had stability problems when using pcap in my little
application. My application is a simple benchmark applications that is
trying to see how much data I can send and receive.
It has one lcore per NIC, where each lcore handles transmit and
receive. On the hardware, I make a loopback between
Hi Mats,
yes, you are right, there is an issue in the pcap driver that it is not
allocating mbufs correctly. We are working on a fix.

Compilation fixes for ICC
ICC requires an initializer be given for the static variables, so
adding one in cases where one wasn't previously given.

Hi Bruce,
We also found buffer overflow problems with the pcap driver. 1) Frame may
be longer than mbuf. 2) Caplen may be less than original packet.
I've been meaning to submit a change, but I'm not familiar with the process.
Here is a diff of the relevant code in rte_eth_pcap.c:
