[ofa-general] What should a ULP pass as ib_create_cq(..., comp_vector) ?

[Talpey, Thomas]

I notice the ib_create_cq() comp_vector support is merged in 2.6.22.
I don't completely understand what a ULP needs to pass as the argument.

I'm currently passing 0 in the NFS/RDMA client, what in general should I
consider using as a value? Or put another way, why is this exposed to
the ULP? Isn't this the MSI-X vector table index, a rather low-level thing
to hand to the ULP to manage?

Thanks,
Tom.
