Removing tu0?

Hello,

We have a AS 2100 with the standard netcard (tu0) and a 10/100 (tu1) one.
We don't use tu0 to anything, but why can't it be deleted? I can get it
down,
but not deleted. But if I put it down, something still tries to do something
to it, because this leads to the "no buffer space available" and this also
leads to a crash of the whole system. But if I leave it up, this also
happens,
but much later.

This is what I have:

xxxx root > ifconfig -a
tu0: flags=c63<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST,SIMPLEX>

tu1: flags=c63<UP,BROADCAST,NOTRAILERS,RUNNING,MULTICAST,SIMPLEX>
     inet 192.xx.x.xx netmask ffffff00 broadcast 192.xx.x.255 ipmtu 1500

sl0: flags=10<POINTOPOINT>

lo0: flags=100c89<UP,LOOPBACK,NOARP,MULTICAST,SIMPLEX,NOCHECKSUM>
     inet 127.0.0.1 netmask ff000000 ipmtu 4096

        As you see something is sending something to tu0. I found out, that
        lat was one of the bad guys, but that i corrected with: latcp -e
tu1
        Now i still have this.. How do I prevent these?

tahma root xterm > tcpdump -i tu0
tcpdump: listening on tu0
