[dpdk-stable] patch 'net/hns3: clear hash map on flow director clear' 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 06/14/21. 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/6ed898b2971caa51fe2542911e301f57550f7e95

Thanks.

[ upstream commit 7d01f89fa6a149157f77ef11a2b5ebec890d7db8 ]

The fdir hash map hold the pointers of fdir rule elements, it needs to
be set to NULL when clear all fdir rules.
