Ya.  The sun2 "ec" driver is for the 3Com 3c400 card, a very simple
Multibus ethernet adapter.  SunOS also called it "ec".  My
understanding is that you can reuse an MI device name when you don't
or can't use the MI driver.

The new MI "sc" entry is for the Sun-2 SCSI driver I added to
sys/dev/vme.  It compiles, but I can't test it because I don't have
VME hardware.  The Multibus version does some useful work tho.
