Actually, OpenBSD supports the following:

SUNW,qfe: 4 port 10/100mb hme boards
SUNW,hme: 1 port 10/100mb hme boards
qec+be: 1 port 10/100mb board with QEC DMA engine
qec+qe: 4 port 10mb board with QEC DMA engine

I personally have one of each of these boards running in OpenBSD machines
(except for SUNW,hme, but I do have SUNW,qfe), And it should be easy
enough to port to NetBSD, but I haven't looked at doing it.

Here's dmesg output from each, which provides a clue to telling one from
another:

qec+qe:

qe3 at qec1 offset 0x0 pri 5: rev 1 address 08:00:20:0b:cb:f1

Note the attachments: hme attaches directly to the sbus (each hme handles 
its own dma (logically), but the qe & be devices attach to a qec carrier,
which is attached to the sbus.
