AFAIK the system has no support for multiple MAC yet. There are two points in the driver missing I know of. The first one is promiscuous support, this should be nothing more than adding the flag and seting the device bit. It wasn't on my list of things to do, because I have a switch soldered onboard, which have to be configured for promiscuous as well. The second one is add support for polling. Polling is a feature, which has showed positive effects on many small systems such as soekris. I asume polling support for ate to be a big win. Then tcpdump crashes with an unaligned fault when tracing ate - it does run when I trace ng interface. This is likely userland problem, but it is interesting that it doesn't happen with ng. Maybe just a matter of packets - who knows. -- B.Walter http://www.bwct.de http://www.fizon.de bernd@bwct.de info@bwct.de support@fizon.de
