patch 'net/ice/base: fix masking when reading context' has been queued to stable release 23.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/14/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=bd5b88d172021a010c131ea3ae3b1c8af919dc12

Thanks.

[ upstream commit 045ff68c49244d998933ef74a719b96db0e43988 ]

No need to invert mask since we only reserve the masked bits instead of
clear them.

Fixes: a03c714bfe0b ("net/ice/base: add two helper functions")
