E.g.: "nic_AMDA0145-1012_2x10.nffw". In practice there may be many variants for each NIC type, and many of the variants relate to assembly components which do not concern the driver and application firmware implementation. Yet the current scheme leads to a different application firmware file name for each variant, because they have different AMDA information. To reduce proliferation of content-duplicated application firmware images or symlinks, the NIC's management firmware will only expose differences between variants that need different application firmware via a newly introduced hwinfo, "nffw.partno". Use of the existing hwinfo, "assembly.partno", is maintained in order to support for NICs with management firmware that does not expose "nffw.partno".
