Note, this is not at all NetBSD-centric..

Last week I posted, asking about setting up ATM in a crossover.

Some said yes, some said no.

Well, I have now managed to get to FORE SBA-200 cards talking to
each other, running FORE's latest drivers with Solaris 2.6/7.

I did have to manually configure the ATM card addresses (NSAP?)
and have not used any VC's, high redundancy/failure, etc, options.

# ifconfig fa0
fa0: flags=842<BROADCAST,RUNNING,MULTICAST> mtu 9188
        inet 192.168.8.2 netmask ffffff00 broadcast 192.168.8.255
        ether 0:20:48:6:9:8a 

on the other host:
# ifconfig fa0
fa0: flags=843<UP,BROADCAST,RUNNING,MULTICAST> mtu 9188
        inet 192.168.8.1 netmask ffffff00 broadcast 192.168.8.255
        ether 0:20:48:6:9:56 

It is somewhat interesting to compare using FDDI with ATM (both in
a loopback setup between the two hosts):

FDDI:
# spray -c 100 -l 4100 192.168.6.1 -d 0
sending 100 packets of length 4100 to 192.168.6.1 ...
        9 packets (9.000%) dropped by 192.168.6.1
        1182 packets/sec, 4849737 bytes/sec

ATM:
# spray -c 100 -l 4100 192.168.8.1 -d 0
sending 100 packets of length 4100 to 192.168.8.1 ...
        33 packets (33.000%) dropped by 192.168.8.1
        929 packets/sec, 3809140 bytes/sec

oh, the ifconfig for the FDDI card looks like this:
nf0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST> mtu 4352
        inet 192.168.6.2 netmask ffffff00 broadcast 192.168.6.255
        ether 0:80:d8:10:21:5f
