Subject: [dpdk-dev] [PATCH] net/iavf: fix vertor interrupt number configuration error
Date: Tue, 19 Mar 2019 11:04:40 +0800 [thread overview]
Message-ID: <1552964680-45860-1-git-send-email-wei.zhao1@intel.com> (raw)
Message-ID: <20190319030440._gAIH_jAAJ0IwSNDBBNPC29d0mzwqzSvmt-gXBjLTz8@z> (raw)
There is a issue when iavf do vertor interrupt configuration,
it will miss one interrupt vector which set admin queue interrupt
when communicate with host pf.
Fixes: 69dd4c3d0898 ("net/avf: enable queue and device")
