Subject: [dpdk-dev] [PATCH 2/4] net/ixgbevf: set the inter-interrupt interval for EITR.
Date: Thu, 26 Oct 2017 06:44:42 -0700 [thread overview]
Message-ID: <1509025484-15771-2-git-send-email-xiangxia.m.yue@gmail.com> (raw)
In-Reply-To: <1509025484-15771-1-git-send-email-xiangxia.m.yue@gmail.com>
From: Tonghao Zhang <zhangtonghao@didichuxing.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.
