patch 'net/e1000/base: fix NVM loop bounds and pointer access' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/27/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/c6936a6137f3ff1e8815395306d3741f62d5b3d3

Thanks.

Kevin

Subject: [PATCH] net/e1000/base: fix NVM loop bounds and pointer access

[ upstream commit 39fba42d04baf045452b224f44dcd9aea38c5b60 ]

Improve the NVM checksum routines by ensuring loop bounds are compared
at the correct integer width. Use array indexing instead of explicit
pointer arithmetic.

Fixes: af75078fece3 ("first public release")
