Greptile Summary

The PR updates the staged DOCA/OFED driver version from doca3.5.0-26.07-0.6.4.0-0 to doca3.5.0-26.07-0.6.8.0-0.

• Updates the OFED driver version consistently across seven example NicClusterPolicy resources.
• Updates both the standard and STIG/FIPS driver entries in hack/release.yaml.

Confidence Score: 5/5

The PR appears safe to merge with no concrete defects identified in the coordinated driver-version update.

The new version satisfies the repository’s version format, all affected example resources and both release entries are synchronized, and existing release automation validates manifest compatibility and image-tag coverage.
