I'm struggling to understand what your card does then. From this, it sounds
like a standard network card that just happens to use IB physicals. Do you just
send raw packets? How is the LRH formatted by your card? I.e. what's setting
up the dlid, slid, vl, etc.? Can your card interoperate with other IB devices
on the network when running in this mode?
