Can someone explain to me why sbappend() is used in tp_stash(),
tp_indicate, and tp0_stash()?  It appears they're used only for
the receive socket buffer... as I understand it, the TP protocol
has message boundaries, and thus should be using sbappendrecord()
in these places, not sbappend().  The same goes for spp_reass()
in netns.

I'm trying to clean up some nastiness in sbappend(), and would
appreciate some insight on these uses of it.
