Members
Connect
The number of outbound connections established. In a bitmask of counters (for example, MissingCounterMask member of the NDIS_NDK_CAPABILITIES structure), this is counter 0.
Accept
The number of inbound RDMA connections established. In a bitmask of counters (for example, MissingCounterMask member of the NDIS_NDK_CAPABILITIES structure), this is counter 1.
ConnectFailure
The number of inbound and outbound RDMA connect attempts that failed. In a bitmask of counters, this is counter 2.
ConnectionError
The number of established connections with an error before a consumer disconnected the connection. In a bitmask of counters, this is counter 3.
ActiveConnection
The number of active RDMA connections. In a bitmask of counters, this is counter 4.

CQError
The number of RDMA completion queue (CQs) that went into an error state. In a bitmask of counters, this is counter 25.
RDMAInOctets
The number of bytes for all incoming RDMA traffic. This should include additional layer two protocol overhead. In a bitmask of counters, this is counter 26.
RDMAOutOctets
The number of bytes for all outgoing RDMA traffic. This should include additional layer two protocol overhead. In a bitmask of counters, this is counter 27.
RDMAInFrames
The number, in frames, of layer two frames that carry incoming RDMA traffic. In a bitmask of counters, this is counter 28.
RDMAOutFrames
The number, in frames, of layer two frames that carry outgoing RDMA traffic. In a bitmask of counters, this is counter 29.
Remarks
The NDIS_NDK_PERFORMANCE_COUNTERS structure is used in the CounterSet member of the NDIS_NDK_STATISTICS_INFO structure.
NDK providers are required to support all the performance counters that are included in the NDIS_NDK_PERFORMANCE_COUNTERS structure. However, in the rare case that a provider cannot support a counter due to extreme implementation difficulties, the provider must indicate any unsupported counters with the mask value for the counter which it cannot support. The MissingCounterMask parameter of the NDIS_NDK_CAPABILITIES structure specifies a bitmask that identifies counters that an NDK provider does not support.
All ReservedXX counters must be set to zero by providers and are ignored by NDIS. The term RDMA refers to all NDKPI and NDSPI activity as well as activity through any other RDMA programming interface that might be exposed by the provider. All providers must report the NDKPI and NDSPI activity with these counters, but reporting activity for other RDMA programming interfaces is not a strict requirement. The term RDMA traffic for the RDMA in, out, byte, and frame counters refers to all RDMA activity originating from NDKPI, NDSPI, and other RDMA programming interfaces (if any). This includes reads and writes (that is, direct data placement) as well as sends and receives. This also should also include all of the associated layer two protocol overhead. That is, RDMA traffic on an NDK-capable adapter includes all traffic through the adapter except for traffic that is delivered through the standard NDIS send and receive interface and TCP chimney by NDIS protocol drivers.
