The structure is the processed receive and trasmit microcode.  That is, the
structure is in the file, xmt.x, that results from compliling xmt.uc and
postprocessing it.  It is available after you 'make' in
Vera/libIXPRouter/ue/src.

When you say "loading mechanism" do you mean the way we place microcode at the
microengines for execution?  Also, do you want a description of what the
loading mechanism does, or how to use it?
