EFA PCIe device implements a single Admin Queue (AQ) and Admin Completion
Queue (ACQ) pair to initialize and communicate configuration with the
device. Through this pair, we run set/get commands for querying and
configuring the device, create/modify/destroy queues, and IB specific
commands like Address Handler (AH), Memory Registration (MR) and
Protection Domains (PD).
In addition to admin (AQ/ACQ), we have data path queues that get
classified as Queue Pairs (QP) and Completion Queues (CQ).
