[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/17/25. 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://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/d94d788b4990d9d47739ef59e407b82196fc6249

Subject: [PATCH] common/cnxk: fix DPI mailbox structure

[ upstream commit b03c474188383c3d3d529b1c9ca86767e5fb6167 ]

In the existing DPI mailbox structure, one of the fields
spans a 64-bit boundary, making it appear unusual and
complicatng extraction using bit operations.

Patch enlarges csize fields to ensure that mailbox fields
are correctly positioned.

Fixes: b6e395692b6d ("common/cnxk: add DPI DMA support")
