The documentation about how to use the mechanisms is available with the IXP
application tarball.

Yes, it does.  If you look at the makefile in the libixprouter/ue/src directory
you will see the process for converting a microcode source file to a *.x file
that contains a uCodeInfo structure.  Basically we compile the microcode, take
the compiled code postprocess it, and write it into the instruction memory of
the microengines.  The code in libixprouter/sa/src/control.c is documented and
shows how the code is loaded to the microengines.

I will try to answer in more depth in a following email.
