patch 'usertools/pmdinfo: fix search for PMD info string' has been queued to stable release 25.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/23/26. 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/8cc1da5351d2986ec6c0dc6583ceedb17c31a78b

Thanks.

Kevin

Subject: [PATCH] usertools/pmdinfo: fix search for PMD info string

[ upstream commit 93389614bfe67e832ccbc379eb0a76c5041b3a29 ]

The PMD_INFO_STRING constant string is not guaranteed to appear in the
output binary immediately after an unprintable character. Because of
this, in some cases the information for a driver could be missed by the
PMD info script as it only checks for the prefix at the start of strings
that it finds. Change the script to use "s.find()" rather than
"s.startswith()" to fix this issue.

Fixes: 0ce3cf4afd04 ("usertools/pmdinfo: rewrite simpler script")
