Hi,
I just installed NetBSD 0.9 on a machine with a 
NE2000-clone ethernet card, which is using the
ne0 driver.  I noticed that when I Pinged another
machine, I would get back 2 replys for every
echo request ping thought it sent out.  When I looked
at the traffic with a lanalyzer, I noticed that my
machine was indeed sending out two packets for every one
it thought it was sending out. It seemed to be doing 
this with ARP packets also.  Is this a configuration 
problem?  I also noticed that ifconfig says that
the interface is configured with the SIMPLEX flag on,
but I can't find any documenation on this.  Could this
flag have anything to do with the problem? Thanks
for any help!
