Subject: [dpdk-dev] [PATCH v4] net/iavf: fix Tx interrupt vertor configuration error
Date: Tue, 26 Mar 2019 13:07:59 +0800 [thread overview]
Message-ID: <1553576879-8824-1-git-send-email-wei.zhao1@intel.com> (raw)
Message-ID: <20190326050759.XZesMSHkVhT7pstIFacDGJmPcci0xMnhR04EG1_LZB8@z> (raw)
In-Reply-To: <1553568050-13343-1-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")

v2:
update git log and add new work around
v3:
update git comment and change fix code as suggestion
v4:
add txq_map in struct avf_info to keep vector mapping info
