I have a SPARCstation IPX running NetBSD 3.0.  Wanting to use it as a
router, I bought a used Sun Quad Fast Ethernet SBUS card on eBay,
checking the list of supported hardware at first to ensure that
it was supported by NetBSD.  I thought it was, because the list said:

   qfe; four 100 Mbps full-duplex "Happy Meal" ethernet interfaces - sbus card 

However, after I installed the card, the machine paniced on boot:

  hme0 at sbus0 slot 2 offset 0x8c00000 level 4 (ipl 5): Sun Happy Meal 
Ethernet (SUNW,qfe)
  hme0: Ethernet address 08:00:20:89:b3:b0
  async mem arr: ser=0 sva=0xffe70000 aer=20<TIMEOUT> ava=0xfe02a00c
  parity error register = 0
  panic: memory error

I now see that the entry for hme in the list of supported hardware
says that it is not supported on sun4c; apparently this also applies
to qfe, but there is no corresponding note on the entry for qfe, and
that was the entry I checked since it exactly matched the hardware I
was buying.



In, add the note "This
hardware is not supported on the sun4c platform" to the entry for qfe,
