patch 'net/i40e: remove redundant judgment in flow parsing' has been queued to stable release 21.11.7

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/11/24. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/3c1d8f321d84a9a2595884ffaadf80b008f636c3

Thanks.

Kevin

Subject: [PATCH] net/i40e: remove redundant judgment in flow parsing

[ upstream commit e930f8622e05e410a475c6b57dd7edd73b2e1705 ]

if (eth_spec && eth_mask &&
	       next_type == RTE_FLOW_ITEM_TYPE_END) {
            ...
            if (next_type == RTE_FLOW_ITEM_TYPE_VLAN || ...) {
            ...
            }
...
}

Clearly, that condition in the inner "if" is always "false".

This commit will remove the redundant judgment.

Fixes: 7d83c152a207 ("net/i40e: parse flow director filter")
