The solution to my problem is:  NIT support was not configured into the
kernel -- the default for clients.  In retrospect, of course, the the
cause seems obvious.  It never occurred to me that there'd be a fs entry
without appropriate kernel support configured.  Talk about naive!  Anyway,
the solution is to cd to the germane /sys/sun??/conf directory and make
sure that the following lines are included in the configuration file you
wish to use:

pseudo-device   snit            # streams NIT
pseudo-device   pf              # packet filter
pseudo-device   nbuf            # NIT buffering module
pseudo-device   clone

Next, run config and then remake the kernel etc.  Thanks to those who
responded and so nicely, too.
