[dpdk-dev] Errors Rx count increasing while pktgen doing nothing on Intel 82598EB 10G

[Zhang, Helin]

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!

Helin

Hi,

I had to reuse my DPDK machines for another task, I will go back to it after FOSDEM.

The error you get is the same as mine.
