patch 'net/fm10k/base: fix compilation warnings' has been queued to stable release 23.11.5

[Xueming Li <xuemingl@nvidia.com>]

Hi,

FYI, your patch has been queued to stable release 23.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/28/25. 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=b632b29cb86c7f74f2d6114f552d7240b6d25009

Thanks.

Subject: [PATCH] net/fm10k/base: fix compilation warnings
Cc: Xueming Li <xuemingl@nvidia.com>

[ upstream commit 48fc5188aa753824a4bd469f9c482e845404c963 ]

The fixes required to re-enable warnings in the fm10k base code are
trivial, so let's make the changes and get a clean compile without any
warning disable flags.

* provide definitions for the UNREFERENCED_PARAMETER macros
* fix the spelling of the work "fallthrough" in comments
* provide a definition of FM10K_READ_PCI_WORD in os_dep.h that marks the
  parameters as used.

Fixes: 7223d200c227 ("fm10k: add base driver")
