To be confirmed, so your point is that the max-read-sges will be different even the transport is the same IWRAP, and that depends on the capability of adapter, correct? I currently only find this one place where infer max-read-sges from transport type, it looks more like a special case to me rather than a generic method we could exposed... and also not very related with IB management helper concept IMHO.
