Properties

Properties

The MSFT_NetAdapter_RdmaAdapterInfo class has these properties.

DeviceId

Data type: uint32
Access type: Read-only

Vendor defined device ID

FRMRPageCount

Data type: uint32
Access type: Read-only

Fast-register memory region (FRMR) size (in PAGE_SIZE pages) for which the adapter supports the most number of FRMRs

InOrderDMA

Data type: boolean
Access type: Read-only

Whether the provider writes incoming data into the client's buffer in order, i.e., the last byte position in the client's buffer is guaranteed not to be updated before any prior byte position.

LargeRequestThreshold

Data type: uint32
Access type: Read-only

Data size hint (in bytes) above which read and write operations will yield better results than send and receive operations

MajorVersionNumber

Data type: uint16
Access type: Read-only

NDKPI Major Version Number

MaxCalleeData

Data type: uint32
Access type: Read-only

Maximum size, in bytes, of the private data that can be sent via an accept or reject request

MaxCallerData

Data type: uint32
Access type: Read-only

Maximum size, in bytes, of the private data that can be sent via a connect request

MaxCompletionQueueDepth

Data type: uint32
Access type: Read-only

Maximum number of completion entries per completion queue

MaxInboundReadLimit

Data type: uint32
Access type: Read-only

Maximum number of in-progress incoming read operations per QP

MaxInitiatorQueueDepth

Data type: uint32
Access type: Read-only

Maximum number of outstanding requests per initiator queue

MaxInitiatorRequestSge

Data type: uint32
Access type: Read-only

Maximum number of SGEs that can be specified in a single request over an initiator queue

MaxInlineDataSize

Data type: uint32
Access type: Read-only

Maximum amount of inline data in bytes that can be sent in a single send or write request

MaxOutboundReadLimit

Data type: uint32
Access type: Read-only

Maximum number of in-progress outgoing read operations per QP

MaxReadRequestSge

Data type: uint32
Access type: Read-only

Maximum number of SGEs that can be specified in a read request (This overrides the MaxInitiatorRequestSge value for read requests.)

MaxReceiveQueueDepth

Data type: uint32
Access type: Read-only

Maximum number of outstanding requests per receive queue

MaxReceiveRequestSge

Data type: uint32
Access type: Read-only

Maximum number of SGEs that can be specified in a single request over a receive queue

MaxRegistrationSize

Data type: uint64
Access type: Read-only

Maximum size (in bytes) of a single memory registration that the adapter can address.

MaxSharedReceiveQueueDepth

Data type: uint32
Access type: Read-only

Maximum number of outstanding requests per shared receive queue. 0 means no SRQ support.

MaxTransferLength

Data type: uint32
Access type: Read/write

Maximum total length that can be referenced by all SGEs in a single send, receive, read, or write request

MaxWindowSize

Data type: uint64
Access type: Read-only

Maximum size (in bytes) for a single memory window

MinorVersionNumber

Data type: uint16
Access type: Read-only

NDKPI Minor Version Number

SupportsCompletionQueueResize

Data type: boolean
Access type: Read-only

Whether the provider supports resizing CQ objects or not. If this is false, CQ resize request must NOT be used by the NDK client.

SupportsLoopbackConnections

Data type: boolean
Access type: Read-only

Whether the provider supports loopback connections (from a local network address on a given RNIC to the same local address on the same RNIC).

VendorId

Data type: uint32
Access type: Read-only

Vendor's organizational unique identifier (OUI)
