  - the w11a rbus interface used so far a narrow dynamically adjusted
  rbus->ibus window. Replaces with a 4k word window for whole IO page.
  - utilize rlink protocol version 4 features in w11a backend
  - use attn notifies to dispatch attn handlers
  - use larger blocks (7*512 rather 1*512 bytes) for rdma transfers
  - use labo and merge csr updates with last block transfer
  - this combined reduces the number of round trips by a factor 2 to 3,
  and in some cases the throughput accordingly.
