Sure thing.

Hmmm... why would it need a hash table?  Let's say there's a struct
rdma_device for each rdma_device and then that stuct can simply have
rdma_device->res_table[] or whatever to track limits and consumptions
and rdma_device->res_enabled mask to tell which resources are enabled
on the device.

Thanks.
