- Work Queues - host-to-adapter for fast-path traffic
- Mailbox Queues - host-to-adapter for control (slow-path)
- Buffer Queues - host-to-adapter for posting buffers for async receive
- Completion Queues - adapter-to-host for posting async events,
       completions for fast or slow patch work, receipt of async
       receive traffic
- Event Queues - tied to MSI-X vectors, binds completion queues with
       interrupts

These patches add the all the support code to tie into command submission
