Subject: [dpdk-dev] [PATCH v6 7/8] igb: enable rx queue interrupts for PF
Date: Fri, 27 Feb 2015 12:56:15 +0800	[thread overview]
Message-ID: <1425012976-10173-8-git-send-email-cunming.liang@intel.com> (raw)
In-Reply-To: <1425012976-10173-1-git-send-email-cunming.liang@intel.com>

From: "Zhou, Danny" <danny.zhou@intel.com>

The patch does below for igb PF:
- Setup NIC to generate MSI-X interrupts
- Set the IVAR register to map interrupt causes to vectors
- Implement interrupt enable/disable functions
