It means that the deqna driver has received a packet > 2K bytes long.
Normal ethernet packets are limited to ~1500 bytes, but many systems
will generate longer packets if left to their own ends.  If you have
a Sun on your net, you should be able to use the etherfind/tcpdump
utilities to get some handle on this.

I've heard that sun NFS will use big packets, but there are parameters
in fstab to control this.  I don't see right off why you would have
problems with rlogin/telnet type protocols though.
