- Update to firmware 1.4.39 for dual-chip NIC (10G-PCIE2-xxx) support, and SFP+ i2c support - Identify newer "B" NICs (10G-PCIEx-8B-x) correctly, rather than mis-identifying them as "A" NICs (cosmetic only) - Identify the IFM_10G_LRM ifmedia type, where applicable. - Identify ifmedia types for SFP+ based NICs - Update copyright Sponsored by: Myricom MFC after: 1 week
