Yeah, I'm slightly unhappy with this whole setup.
If we were just doing DIF I guess the setup could work, but then we have to
disable DIX (as we cannot support integrity data on the non-PI path).
But we would need an additional patch to disable DIX functionality in those
cases.
NVMeoF only supports inline integrity data, the remapping from out of
line integrity data is always done by the HCA for NVMe over RDMA,
and integrity data is not supported without that.
Because of that I can't see how we could sensibly support one path with
integrity offload and one without. And yes, it might make sense to
offer a way to explicitly disable integrity support to allow forming such
a multipath setup.
I agree. I didn't read through the change log well enough, I thought
that one path is DIF and the other is DIX.
I agree that we should not permit such a configuration.
