You can think of an E1000 as a standard rack mount storage server with 24
NVMe slots.  They are often used as Lustre servers.  The DMI check makes
sure the E1000 LED driver can only be loaded on E1000 boards.  The driver
is running on the main system (where Lustre runs) rather than a embedded
storage controller. The driver does communicate with a embedded
controller via IPMI to control the LEDs though.

I'm currently on baby bonding leave, but I'll try to implement your review
comments into a version 3 patch once I get back into the office.
