I just looked at the code, and it doesn't attempt to include
generally-specified options in the PXE-proxy reply, only the stuff
required for the PXE protocol. Do you know that what you're trying to do
is valid (ie send general options via the PXE-proxy reply, rather than
have the client get them from the server which does address allocation.)?
It may be time to consult the Intel PXE specification. Abandon hope......
