The problem I found with the increasing RX errors is because a stats register was being read that does not exist in that given chipset and removing that register read would eliminate the false errors you were seeing. Here is part of the email I sent to Laurent. Hi Laurent, Well, it appears the problem is on the ixgbe driver the fccrc and fclast hw stats are not supported on 82598 only the 82599+ devices. On t3 you can look at the ixgbe_ethdev.c code I modified to remove these two stats, which caused ierrors to increase. You can also revert any changes in Pktgen to master as they did not help fix any thing. Sorry is it 6 am and I need to sleep some, I could not sleep tonight, so you I was able to debug the problem. Please remove the debug code in the ixgbe driver if you like as well and move that change to t1 machine. I will report this to the list later. The performance of pktgen/DPDK was not being effected by these counters. Thanks ++Keith

[dpdk-dev] Errors Rx count increasing while pktgen doing nothing on Intel 82598EB 10G
Helin, I implemented my own sample application that is a kind of carrier
grade NAT server.
It works fine on 1G NIC (i.e. Intel Corporation 82576 Gigabit Network
Connection (rev 01))
But, it does not receive packets on 10G NIC (i.e. Intel Corporation 82598EB
10-Gigabit AF Network Connection (rev 01)) as described in the previous
email.
According to my log messages, it seems that control register for RX DMA is
not enabled.
Here is some information about my environment.

I'm going to update firmware of my NIC, but I'm not sure it helps.
I appreciate any comment.

Laurent, have you resolved this problem? I'm using the same NIC as yours (i.e. Intel 82598EB 10G NIC) and faced the same problem as you. Here is parts of my log and it says that PMD cannot enable RX queue for my NIC. I'm using DPDK 2.2.0 and used 'null' for the 4th parameter in calling rte_eth_rx_queue_setup(). (i.e. 'null' parameter provides the default rx_conf value.) Thanks. APP: initialising port 0 ...

Moon-Sang Were you using pktgen or else application? Could you help to share with me the detailed steps of your reproducing that issue? We will find time on that soon later. Thanks!

Change the [2:3].1 to [2:3].0 the reason is you removed one of the two ports and Pktgen starts port counting from zero for the first available port :-) Sorry, I did not spot that sooner. > >The two "-f" pkt files are attached to this email, I do "start 1" >manually at the pktgen prompt. > >Thanks for your time, > >Sincerely, > >Laurent > > >> > >> >Laurent >> > >> > >> >> >> Regards, >> Keith >> >> >> >> > > Regards, Keith

Hi, I reported today an issue when using Pktgen-DPDK: https://github.com/pktgen/Pktgen-DPDK/issues/52 But I think it's more in DPDK than pktgen two identical machines with SFP+ DA cable between them DPDK 2.2.0 from tarball Pktgen-DPDK from git two identical machines: core i7 2600 (sandy bridge 4C/8T), HT disabled in the BIOS ASUS P8H67-M PRO BIOS 3904 (latest available) Ethernet controller: Intel Corporation 82598EB 10-Gigabit AF Dual Port Network Connection (rev 01) 01:00.0 0200: 8086:10f1 (rev 01) Subsystem: 8086:a21f boot kernel 3.16 unbutu 14.04 with isolcpus=2,3,4 When launching pktgen even with no TX asked the Errors RX counters keeps going up by about 7.4 millions per second: Errors Rx/Tx : 7471857054/0 In the log I get "Could not enable Rx Queue", might be the source of the issue? PMD: ixgbe_dev_rx_queue_start(): Could not enable Rx Queue 0 PMD: ixgbe_dev_rx_queue_start(): Could not enable Rx Queue 1 When sending traffic single UDP src/dst/IP/MAC the setup reaches 14204188 pps 64 bytes, the error counter is also increasing. Any idea what to look for? Laurent
