patch 'net/hns3: reimplement hash flow function' has been queued to stable release 22.11.2

[Xueming Li <xuemingl@nvidia.com>]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/11/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging/commit/3a5105f1de819eed82a669824012f6d7dd556994

Thanks.

Subject: [PATCH] net/hns3: reimplement hash flow function
Cc: Xueming Li <xuemingl@nvidia.com>

[ upstream commit e3069658da9ffb6f83a0d972ff2776c405eb6a8f ]

Currently, hns3 driver supports setting multiple rte flow RSS rule,
but only the last is valid. This implementation is different from
the mainstream usage of rte flow hash in the community. Please see
the discussion threads [1] and [2].

This patch sets RSS hash feature completely based on the request of
the flow rule so that multiple hash rules can take effect at the same
time. Please notice that:
1. For hns3, 'func' has only one hardware. 'key' and 'queue' have only
   one entry in hardware.
2. the overlapping part of the old rule will be overridden if the
   configuration items of a new rule overlap with those of an old rule.

The hns3_flow_validate() verifies and parses RSS or Fdir rules from
user, and saves them to a local variable at the same time. The local
variable is directly used to create RSS or Fdir rules. In this way,
we save one parsing and saving process.
