Module primitives 

This file contains primitive data structures for interacting with ibverbs.

Primitives:

• IbvConfig: Represents ibverbs specific configurations, holding parameters required to establish and manage an RDMA connection, including settings for the RDMA device, queue pair attributes, and other connection-specific parameters.
• IbvDevice: Represents an RDMA device, i.e. ‘mlx5_0’. Contains information about the device, such as: its name, vendor ID, vendor part ID, hardware version, firmware version, node GUID, and capabilities.
• IbvPort: Represents information about the port of an RDMA device, including state, physical state, LID (Local Identifier), and GID (Global Identifier) information.
• IbvMemoryRegionView: Represents a memory region that can be registered with an RDMA device for direct memory access operations.
• IbvOperation: Represents the type of RDMA operation to perform (Read or Write).
• IbvQpInfo: Contains connection information needed to establish an RDMA connection with a remote endpoint.
• IbvWc: Wrapper around ibverbs work completion structure, used to track the status of RDMA operations.

Structs
