I have been told that "le" is "lance ethernet", I can only hope that some dude named "Lance" invented the thing. Can anyone explain these names?
Actually hme as "happy meal" is a deliberate misinterpretation of the acronym which started internally at Sun. hme formally means "Hundred Megabit Ethernet".
ce0 - Cassini was the Sun project code name for the "Gigaswift" chipset.
le - Lance ethernet Comes from the use of the Lance Am7990 chip.
eri is an reverse of the normal pattern -
Ethernet
Rio because the Rio ASIC is used. This reverse naming might be because the RIO is both an IO and ethernet controller and only the ethernet tracnciever is used.

HME(4) BSD Kernel Interfaces Manual HME(4)
NAME
hme -- Sun Microelectronics STP2002-STQ Ethernet interfaces device driver
SYNOPSIS
hme* at pci? dev ? function ?
hme* at sbus? slot ? offset ?
DESCRIPTION
The hme driver supports Sun Microelectronics STP2002-STQ Fast Ethernet interfaces.
HARDWARE
The hme driver supports the on-board Ethernet interfaces of many Sun UltraSPARC workstation and server models.
Cards supported by the hme driver include:
Sun PCI SunSwift Adapter (``SUNW,hme'')
Sun SBus SunSwift Adapter (``hme'' and ``SUNW,hme'')
Sun PCI Sun100BaseT Adapter 2.0 (``SUNW,hme'')
Sun SBus Sun100BaseT 2.0 (``SUNW,hme'')
Sun PCI Quad FastEthernet Controller (``SUNW,qfe'')
Sun SBus Quad FastEthernet Controller (``SUNW,qfe'')
The STP2002 family supports hardware checksumming to assist in computing IPv4 TCP/UDP checksums. The hme driver supports this feature of the
chip. See ifconfig(8) for information on how to enable this feature.

http://mediacast.sun.com/users/Barton808/media/STP2002QFP-FEPs_UG.pdf, April 1996.
HISTORY
The hme driver first appeared in NetBSD 1.5.
AUTHORS
The hme driver was written by Paul Kranenburg <pk@NetBSD.org>.
BUGS
Connecting a MII transceiver on those cards that support it will cause the RJ45 connector to be detected as PHY instance 1, instead of the
default instance 0.
