Subject: [dpdk-dev] [v4]net/hinic: fix coredump when the scondary process using the hinic port.
Date: Sat, 31 Oct 2020 18:23:42 +0800	[thread overview]
Message-ID: <75f84103-ca98-e6b1-1013-c2720189c848@huawei.com> (raw)
In-Reply-To: <836f40cb-57a9-7b02-adcc-dd302a93a722@huawei.com>

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".

---
v4: adapt to the latest version.
---
v3: update the signed-off information.
---
v2:  solve the coding style issue.
