Subject: [PATCH v5 09/22] RDMA/irdma: Implement HW Admin Queue OPs
From: Mustafa Ismail <mustafa.ismail@...el.com>
The driver posts privileged commands to the HW
Admin Queue (Control QP or CQP) to request administrative
actions from the HW. Implement create/destroy of CQP
and the supporting functions, data structures and headers
to handle the different CQP commands
