Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/545c56474be050aee1f38d13c6bffac122654dfd

Thanks.

Luca Boccassi

Subject: [PATCH] net/txgbe: validate numeric devargs

[ upstream commit 3c1652ebd4b05619d1fda677efd57725894b3b1e ]

Be more careful about validating devargs numeric values.
Don't silently truncate to 16 bits, and check for empty
string or trailing garbage.

Fixes: f611dada1af8 ("net/txgbe: update link setup process of backplane NICs")
