This task is for QE verification of the issue described in Epic OSPRH-15524:

• Verizon is testing RHOSP 17.1 (RHEL 9.2) and found that "IPV6_AUTOCONF=no" in the ifcfg file is ignored.
• Even with autoconf and accept_ra disabled, a local IPv6 address is still configured.
• The issue is always reproducible.

Verification Steps:
1. Deploy an environment with RHOSP 17.1 on RHEL 9.2.
2. Configure network interfaces with "IPV6_AUTOCONF=no" in the ifcfg file.
3. Ensure autoconf and accept_ra are disabled.
4. Verify that no local IPv6 address is configured.
5. Document results and discrepancies.

Reference Epic: https://issues.redhat.com/browse/OSPRH-15524

Expected: "IPV6_AUTOCONF=no" should be respected and no local IPv6 address should be configured.
Actual: It is ignored (per Epic).

Please attach logs and test results to this task.
