configuring a packet processing pipeline circuit that includes a plurality of match-action units in a match-action pipeline to create, in a pipeline local memory, a remote DMA (RDMA) administrative data structure for an InfiniBand channel adapter;

configuring a DMA output stage of the packet processing pipeline circuit to copy the RDMA administrative data structure from the pipeline local memory into a memory; and

configuring the match-action pipeline for processing a plurality of network traffic flows that include I/O and InfiniBand traffic flows,

wherein:

the packet processing pipeline circuit is implemented in hardware;

the DMA output stage accesses the memory via a memory interface that is implemented in the hardware;

configuring the packet processing pipeline circuit to create the RDMA administrative data structure includes configuring at least one of the match-action units in the match-action pipeline to create the RDMA administrative data structure in the pipeline local memory; and

wherein the processing of the network traffic flows includes receiving a packet of a network flow and 1) processing the packet by performing an action indicated by a flow table entry for the network flow in response to finding the flow table entry for the network flow, or 2) processing the packet by performing a default action in response to finding no flow table entry for the network flow.
