Subject: [dpdk-dev] [PATCH 2/5] net/ixgbevf: set the inter-interrupt interval for EITR.
Date: Fri, 5 Jan 2018 06:10:36 -0800 [thread overview]
Message-ID: <1515161439-4792-2-git-send-email-xiangxia.m.yue@gmail.com> (raw)
In-Reply-To: <1515161439-4792-1-git-send-email-xiangxia.m.yue@gmail.com>
Set EITR interval as default. This patch can improve the performance
when we enable the rx-intrrupt to process the packets because we hope
rx-intrrupt reduce CPU.
The 200us value of EITR makes the performance better with the low CPU.
