v1.3.5

Fixed

• SR-IOV Configuration Generation: Fixed ENI Manager incorrectly generating SR-IOV device plugin configuration for regular ENI configurations (Case 1) when it should only do so for configurations where SR-IOV is explicitly requested via dpdkPCIAddress field
• PCI Address Mapping: Fixed interface-to-NodeENI mapping logic to prioritize PCI address matching over device index matching for SR-IOV configurations, resolving PCI address mismatches in SR-IOV device plugin configuration
• Resource Name Mapping: Resolved issue where PCI addresses were incorrectly mapped to SR-IOV resource names (e.g., PCI 0000:00:08.0 incorrectly mapped to sriov_kernel_1 instead of sriov_kernel_2)

Added

• Enhanced Logging: Added detailed logging for interface mapping decisions to help troubleshoot configuration issues
• Test Coverage: Added comprehensive test coverage for interface-to-NodeENI mapping scenarios including TestPCIAddressMapping and TestRegularENINoSRIOVConfiguration
• Documentation: Updated GitHub issue #22 with detailed root cause analysis and solution documentation

Changed

• Interface Mapping Logic: Modified findNodeENIForInterface method to check PCI address first for SR-IOV configurations, then fall back to device index for regular ENI configurations
• SR-IOV Logic: Updated updateSRIOVConfiguration method to only process interfaces where dpdkPCIAddress is explicitly specified, ensuring proper separation between regular ENI and SR-IOV functionality

Technical Details

This release addresses critical issues in SR-IOV configuration generation:

1. Issue 1: Regular ENI configurations (no DPDK fields) were incorrectly generating SR-IOV device plugin configuration
2. Issue 2: PCI address mapping was using device index first, causing incorrect associations between interfaces and NodeENI resources

The fixes ensure that:

• Regular ENI configurations work as intended (basic ENI attachment only)
• SR-IOV configurations correctly map PCI addresses to resource names
• Cleaner separation of concerns between regular ENI and SR-IOV functionality
