[dpdk-stable] patch 'net/hinic: fix crash in secondary process' has been queued to stable release 20.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/12/21. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/de81fe259ae6738425d3f761028ec8fe96f70f8c

Thanks.

Subject: [PATCH] net/hinic: fix crash in secondary process
Cc: Luca Boccassi <bluca at debian.org>

[ upstream commit 4c670dfaa417bc5604c9c58b505a74e2725acdb2 ]

Some apps, such as fstack, will use secondary process to access the
memory of eth_dev_ops, and they want to get the info of dev, but hinic
driver does not initialized it when in secondary process.

Fixes: 66f64dd6dc86 ("net/hinic: fix secondary process")
