Rather than having > one global module parameter. The HCA has set of per port buffers, from which comes the dependency between VLs to MTU. So with this code running for each IB hca/port, we're actually doing that logic port-by-port. I assume you didn't mean let the user specify a desired MTU for each hca/port... or I'm still not fully with you? Anyway, I'd be happy to provide at least the folks that use torus/mesh and/or sophisticated QoS schemes an ability to use eight VLs with the current HW, so how about keeping the module param but with default value turned on?
