patch 'net/i40e: fix build with MinGW GCC 12' has been queued to stable release 21.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/01/22. 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/9ba87edbe69cac90bf8aff9714e3724519c633bf

Thanks.

Kevin

[ upstream commit eb440cea1e05245f362ec7fca932f2d977f12359 ]

When compiling with MinGW GCC 12,
the rte_flow_item array is seen as read out of bound:

net/i40e/i40e_hash.c:389:47: error:
    array subscript 50 is above array bounds of ‘const uint64_t[50]’
    {aka ‘const long long unsigned int[50]’} [-Werror=array-bounds]
    389 | item_hdr = pattern_item_header[last_item_type];
        |            ~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~

It seems the assert check done above this line has no impact.
A real check is added to make the compiler happy.

Fixes: ef4c16fd9148 ("net/i40e: refactor RSS flow")
