Subject: [dpdk-dev] [PATCH v9 10/12] igb: enable rx queue interrupts for PF
Date: Fri, 29 May 2015 16:45:23 +0800	[thread overview]
Message-ID: <1432889125-20255-11-git-send-email-cunming.liang@intel.com> (raw)
In-Reply-To: <1432889125-20255-1-git-send-email-cunming.liang@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
