Subject: [dpdk-dev] [PATCH v3] net/iavf: fix Tx interrupt vertor configuration error
Date: Tue, 26 Mar 2019 10:40:50 +0800	[thread overview]
Message-ID: <1553568050-13343-1-git-send-email-wei.zhao1@intel.com> (raw)

In-Reply-To: <1553236034-45852-1-git-send-email-wei.zhao1@intel.com>

There is need to align to kernel iavf code when setting Tx
queue interrupt vector in messge VIRTCHNL_OP_CONFIG_IRQ_MAP,
if not it maybe cause restart iavf port error in some scenario.

Fixes: 69dd4c3d0898 ("net/avf: enable queue and device")
