chained packet panic on DEQNA (uvaxII) ?

Sun's RPC/NFS implementation will use big *UDP* packets - the size of
these is controlled by parameters in "fstab" - but by the time it gets
to the link layer IP should have busted them up into properly-sized
fragments if necessary.  The BSD IP code, which is used in SunOS and,
presumably, Ultrix (and probably 99 44/100% of the UNIX TCP/UDP/IP
implementations out there, as well as a lot of *non*-UNIX
implementations), will do this.

If a machine puts out Ethergrams longer than 1500 bytes, it's being
*very* antisocial, except maybe if it's talking to other consenting
adults.  If you're using Internet-family protocols (TCP/UDP/IP/etc.),
it's basically the responsibility of IP to ensure that your machine is
not being antisocial.
