Examples described herein relate to a network interface device that includes circuitry to process data and circuitry to split a received flow of a mixture of control and data content and provide the control content to a control plane processor and provide the data content for access to the circuitry to process data, wherein the mixture of control and data content are received as part of a Remote Procedure Call. In some examples, provide the control content to a control plane processor, the circuitry is to remove data content from a received packet and include an indicator of a location of removed data content in the received packet.
