Subject: [PATCH 01/15] Apply uncrustify changes to .c/.h files in the
NetworkPkg package
RH-Author: Jon Maloy <jmaloy@redhat.com>
RH-MergeRequest: 56: Pixiefail issues in NetworkPkg package
RH-Jira: RHEL-21840 RHEL-21844 RHEL-21846 RHEL-21848 RHEL-21850 RHEL-21852

RH-Commit: [1/15] 7a6f3c908d076e6497e0c8978785b679a23b83cf
JIRA: https://issues.redhat.com/browse/RHEL-21844
CVE: CVE-2022-45231
Upstream: Merged
Conflicts: This commit is too intrusive to apply completely. We still save
us a lot of problems (git cherry-pick basically bails out) in
the following commits in this series if we apply it on the files
modified by those commits.
