[PATCH 0/3] fix build with MinGW 13

[Thomas Monjalon]

After an upgrade to MinGW version 13, some compilation errors appear
in PCI, mlx5 and bbdev code.
This series fixes them all.

[PATCH 1/3] bus/pci: fix build with MinGW 13

[Thomas Monjalon]

After an upgrade to MinGW version 13, some compilation errors appear:

drivers/bus/pci/windows/pci.c:362:58:
	error: 'GUID_DEVCLASS_NETUIO' undeclared
drivers/bus/pci/windows/pci_netuio.c:57:39:
	error: 'GUID_DEVINTERFACE_NETUIO' undeclared

The cause is MinGW has set NTDDI_VERSION to the highest version
without defining the expected NETUIO constants.

It is safer to not rely on Windows headers version,
and instead define what is not already defined.

[PATCH 2/3] net/mlx5: fix build with MinGW 13

[Thomas Monjalon]

After an upgrade to MinGW version 13, compilation breaks:

drivers/net/mlx5/windows/mlx5_ethdev_os.c:285:69: error:
	'dev_link.<U1000>.<Uaf00>.link_autoneg' may be used uninitialized

This is because link_autoneg is never set in mlx5_link_update().
It can be set to the previous value (no change).
Also it does not make sense to check this value to return the update status
as it does not change.

[PATCH 3/3] bbdev: wrong fix for MinGW 13

[Thomas Monjalon]

After an upgrade to MinGW version 13, compilation breaks:

In function 'rte_bbdev_queue_ops_dump':
lib/bbdev/rte_bbdev.c:1269:63: error:
	'%s' directive argument is null [-Werror=format-overflow=]
	fprintf(f, "  Enqueue Status Counters %s %" PRIu64 "\n",

The enqueue status string may be null if the index is too high,
because RTE_BBDEV_ENQ_STATUS_SIZE_MAX is defined to include
padding for future enum insertion.
This padding case must be checked
to avoid printing a dump of a non-existing status.
