To do that I will need to modify the master_control block, so I will 
make new master_control_inband. The strobe generators are cascaded in 
there, what's the point of this setup?

have_space, tx_empty and tx_underrun are no longer relevant, but they 
are still used by the FX2, right? Can I just force them to (true, false, 
false) all the time?
