I mean set the MTU port-by-port with the module loaded, the same way we are supposed to be able to do for the port type. 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?
