Thanks, but did you see #11846 (comment) ?

@starrysec can you please rework this in a next PR:

1. make sure to review the entries from the PR template
2. review & sign the CLA
3. use a real name commit author setting.
   Thanks!

That means you should also make use of OISF/suricata-verify#2072 (see PR template)

Linked the SV PR here, re-run the CI checks.

Marking this as changes requested as per Philippe's comment ;)

@starrysec we'd like to have your patch merged for our next release.

But for us to be able to merge it, we need the commit author to be the same as we see in the CLA, could you fix that, rebase the code, and submit a new PR?

Closed due to lack of response from PR author.
