Yes.  Thanks for the info about PROM revisions.  I suspect the le
driver differs between those PROM revisions.  It would be helpful to
try a copy of netboot built with -DNETIF_DEBUG for netif_sun.c (in
libsa) and keep track of what length packets are received.  Note
that the PROM sif_poll functions does not let you specify the length
of your receive buffer, so maybe it is overwriting it.  (a hunch)
We might need to allocate a (large) buffer for sif_poll to use as
its actual receive location, and then copy the packet.  (Yuck!)
