Hi,

Is this simulation package based on ofed-1.2.5 or an older version of ofed?
Might it be possible to load different ofed versions in omnet++? 
I'm not aware of the internal structure of omnet++, but I thought it was possible in ns2 to insert different library versions (for instance of tcp).

Kind regards,

Koen
