[dpdk-stable] patch 'common/mlx5: fix pointer cast on Windows' has been queued to stable release 20.11.1

[luca.boccassi at gmail.com]

Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/6c89a5d52f4a0d95726b9b837419ff3f20cefbaa

Thanks.

Luca Boccassi

Subject: [PATCH] common/mlx5: fix pointer cast on Windows

[ upstream commit 5a90a6e40db6e712fd9dc12dedd14d8feb690ff3 ]

While compiling with clang 11 the callers of the
__mlx5_bit_off macro warns on the cast of pointers to
unsigned long which is a smaller int type in Windows.

warning: cast to smaller integer type 'unsigned long'
from 'u8 (*)[16]' [-Wpointer-to-int-cast]

To resolve it the type is changed to uintptr_t to be
compatible for both Linux and Windows.

Fixes: 865a0c15672c ("net/mlx5: add Direct Verbs prepare function")
