So the legacy stack does special things when it sees gPXE/iPXE
underneath it; it talks a custom protocol with iPXE to allow it to use
TCP-based protocols using the stack in iPXE.

The lwIP-based stack shouldn't need to do that, and probably shouldn't,
but it is not well know how much problem the iPXE stack being in between
will cause.  I suspect we need to get the iPXE people involved, though.

We should check, though, that we aren't simply using vestiges of the
custom protocol that is tripping us up.
