Subject: [dpdk-dev] [v3]net/hinic: fix coredump when the scondary process using the hinic port.
Date: Sat, 31 Oct 2020 17:38:48 +0800	[thread overview]
Message-ID: <edf0958a-73e4-b4aa-5cfe-e051681d6e71@huawei.com> (raw)

fix coredump when secondary process using the hinic port.
the reason is that during the stage of
secondary process port initialization,
it lack the initialization of "eth_dev->dev_ops".

Signed-off-by: Qingqing Li <liqingqing3@huawei.com>
