Hi,
One of the objectives of DPDK is avoiding of interrupts, so application
(not only L2FWD) polls NIC infineteley. You can look at programmers guide
section 24 "Power Management" and "L3 Forwarding with Power Management
Sample Application" in Sample Applications User Guide.
Regards,
Vladimir.
You can have a look at Pktgen-DPDK on:
git clone git://github.com/Pktgen/Pktgen-DPDK
Pktgen is a traffic generator using DPDK for L2/L3 and a number of other
features :-)
Hope thats what you are looking for.

Hello,
I've become a member.
I want to ask the following:
I'm looking for Layer2/3 Tx generator (not forward) example.
Thanks,
Ilan
I think I found the problem - it was solved by manually calling
rte_pktmbuf_free for each packet.
It seems that rte_pktmbuf_free is not automatically called from
within rte_eth_tx_burst if packets are sent to pcap device.
Is it possible?

Hello,
Ok. Can you help me with something else ?
Right now, at a rate of 1.3~1.4 Mpps I am having about 4~5% of packet loss,
I wonder if I use my application wth a 10G NIC, will it not be able to cope
with more than 1.4 Mpps ? Because by seeing a packet loss I got a little
afraid of it.
Hi,
Why by default L2FWD saturate both cores ? I mean, it seems it keeps wasting
cycles due to the infinite loop placed there to check the queues.
Which would be the way to improve this and make it to become more efficient
?
Sincerely,
Fred
