Michael,
Different workloads could use different send/recv queue sizes, also different HCAs could pick up different send/recv queue sizes to utilize the HCA performance. These parameters should be tunable instead of setting default values in IPoIB. Also Kevin pointed out, we don't want to waste the kernel memory when not necessary.
Without each HCA vendor support resizing send/recv/completion queue pairs, the tuning method is limited to only as loadable modules. Patch is under testing, and will be available for review soon.
Thanks
