It appears that multiple boards at the same level 2 or level 6
interrupt can be handled at the same time, i.e. 1+N Lance
ethernet cards? The older le driver stomped on multiple cards.
Hm, the le is a bit less modern than the ed (or bah :-) driver last
time I looked. ed should work, bah definitely does work (I have 2
A2060 in my A3000 for tests during development).
Also, it would appear that the ethernet card is in the
isr chain before the internal SCSI controller on a 3000. Would
this have any impact in SCSI vs le wars? It looks like other
SCSI controllers are at 2 as well so does that mean the ethernet
cards will always be processed before the SCSI controllers? Is
this a performance concern? Is there a way to manually
Dont think so. After all, scsi and ether ints should happen only once
a block / packet. High speed serials might be a real problem.
the config order of devices so the SCSI controller would be
configured before the other devices? It appears that a SCSI
controller will always be the last thing to config from the
kernel boot output I've seen.
