Even if I'm not totally aware about what problem are gabor@ is having
at the moment, some time ago I started looking at the code and one
difference between ipi and wpi is in rings they use (and their
allocation) and again in the usage of a shared DMA memory page between
the host and the NIC.

Maybe this is not done in the right way in the Damien's driver and
this is beacause gabor would having allocation problems.

PS: I will try to look at the code posted above ASAP...
