patch 'eal: introduce more macros for bit definition' has been queued to stable release 23.11.7

[Shani Peretz]

Hi,

FYI, your patch has been queued to stable release 23.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/19/26. 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/shanipr/dpdk-stable

This queued commit can be viewed at:
https://github.com/shanipr/dpdk-stable/commit/a1ed4e9b43d451fa656854f8c9c2e6b5a2c68cd2

Thanks.

Shani

Subject: [PATCH] eal: introduce more macros for bit definition

[ upstream commit 1d8f2285ed3ffc3dfbf0857a960915c0e8ef6a8d ]

Introduce macros:
1. RTE_SHIFT_VAL64: get the uint64_t value which shifted by nr.
2. RTE_SHIFT_VAL32: get the uint32_t value which shifted by nr.
3. RTE_GENMASK64: generate a contiguous 64bit bitmask starting at bit
                  position low and ending at position high.
4. RTE_GENMASK32: generate a contiguous 32bit bitmask starting at bit
                  position low and ending at position high.
5. RTE_FIELD_GET64: extract a 64bit field element.
6. RTE_FIELD_GET32: extract a 32bit field element.
