Hi GroundSea,
Please refer to the website for Intel® Data Plane Development Kit (Intel® DPDK) at http://www.intel.com/content/dam/www/public/us/en/documents/release-notes/intel-dpdk-release-notes.pdf
On page 57 Section 8.6, there is a specific section on Latency adjustments.
If the issue still persist, there is a note in the guide :
All Intel® DPDK questions and technical problems including those regarding the Ethernet* Controllers for the Poll Mode Driver should be reported through the Intel®
Premier Support site http://premier.intel.com/premier or access your IBL account and click the Intel® Premier Support link to enter issues under the Product
Name “Data Plane Development Kit (DPDK)”,
Hope this info helps.
