Intel's FreeBSD NVMUpdate utility and NVM images for Intel I225 and I226
Ethernet controllers.  The utility and license files are fetched from Intel's
E610 FreeBSD update package.  Intel's I225 v1.00 package supplies the I225
device 15F2 images and EEPROM map.  The I225-V device 15F3 and I226 images are
fetched from a pinned commit of an unofficial, unsupported GitHub mirror.

The generated configuration is limited to Intel reference subsystem IDs.  It
uses Intel's exact I225 device 15F2 matches and known ETrack lineages for
I225-V and I226-V.  I226-LM and I226-IT entries omit REPLACES so they match the
exact four-part PCI ID regardless of installed NVM version; separate
configurations select each flash-size variant.  The combined configuration is
not supplied, approved, or supported by Intel.
