IXDP is a layer above libxdp/AF_XDP which is responsible for XDP ring management operating with a set of interfaces in promiscuous mode. IXDP registers its specific set of RPCL functions (words) which allow to control and configure the IXDP packet processing layer. This posts explains the IXDP packet processing flow in general and outlines the related RPCL functions (words) for the different stages.

EtherTAP is a software based Ethernet analysis and monitoring security tool which allows to obtain insight and to record selected (or all) traffic for further analysis and evaluation. EtherTAP is based on IXDP, which is an internal API at Inlab Networks on top of libxdp/AF_XDP. XDP/AF_XDP in zero-copy mode allows packet processing at wire-speed up to 100GbE full duplex.
