…NVIDIA#2788) Item #2 of NVIDIA#1076: when both primary Redfish sources for the DPU PF0 base MAC are missing (Systems/Bluefield OEM BaseMAC and the DPU_SYS_IMAGE firmware version), pairing previously hard-failed. Add a third fallback that derives the base MAC from the BMC manager eth0 MAC minus a per-platform offset, only failing the old way if all paths miss. - find_host_pf_mac_address now tries: (1) OEM BaseMAC, (2) DPU_SYS_IMAGE, (3) BMC eth0 - offset; the legacy error is surfaced if path 3 is unavailable so we still "fail the old way". - Offset table keyed on DpuModel via identify_dpu(). BlueField-3 uses a measured offset (0x25); BlueField-2/Unknown are unsupported (return None, never guess). Offset calibrated and documented against a real BF3 DPU and cross-checked with the manual's BMC = OOB + 1 relationship. - Guard against transient pre-sync data: a locally-administered BMC eth0 MAC is rejected for derivation, and fetch_manager logs a warning whenever it sees one (it poisons anything keyed on the BMC MAC). <!-- Describe what this PR does --> ## Related issues <!-- Refer to existing GitHub issues here --> NVIDIA#1076 ## Type of Change <!-- Check one that best describes this PR --> - [ ] **Add** - New feature or capability - [ ] **Change** - Changes in existing functionality - [X] **Fix** - Bug fixes - [ ] **Remove** - Removed features or deprecated functionality - [ ] **Internal** - Internal changes (refactoring, tests, docs, etc.) ## Breaking Changes <!-- If checked, describe the breaking changes and migration steps --> <!-- Breaking changes are not generally permitted, please discuss on a GitHub discussion or with the development team if you believe you need to break a backward compatibility guarantee --> - [ ] **This PR contains breaking changes** ## Testing <!-- How was this tested?
