Re: [dpdk-dev] Intel 82571EB PMD support

[Chetan Bali <chetan.bali@aricent.com>]

Can anyone help me resolve this issue? We have bought the 82571EB dual port NIC and we are not able to run the DPDK pmd userapp on it.

Please update if there is any issue.

Hi Stefan,

It will be of great help if you or anyone else could help me resolve this issue.

I have checked 82571EB on following setup:

OS version: CentOS 6.4 [ kernel 2.6.32.358 ] DPDK version : DPDK 1.6.0-r1

Let me know if any update of centos can help resolve this issue?


Thanks & Regards
Chetan Bali

Chetan,

I saw exactly that behavior with an 82599EB but running DPDK version 1.3.2 and CentOS 6.2 and the fix for me was upgrading to CentOS 6.4 - there was a thread a while back about a bug that caused DD to not be set but I can't seem to find it right now.

I'm sorry I can't be of more help but at least this is a symptom that has been seen before.

Regards,
Stefan

Hi,

Do we have PMD support for intel 82571EB. We are having e1000e driver supported for 82571EB in linux.

DPDK Version : 1.6.0-r1

Linux Kernel : CentOS 6.4 [ kernel version 2.6.32-358.el6.x86_64 ]


Issue:

When we run DPDK example [ l2fwd ], we are able to see successful init of rte_pmd_em and link is also detected successfully.
But the RX, TX count are zero. If we try to fetch nic stats using rte_eth_stats_get(), we can see around 256 ipacket count but after that error count [rx error ] starts increasing.

We are not able to see any packet on user app [ l2fwd ]. Does anyone else face the same issue?

Regards
Chetan Bali
