Data path in linux networking stack
WebNetwork function representors bring the standard Linux networking stack to virtual switches and IOV devices. Just as each physical port of a Linux- controlled switch has a separate netdev, so does each virtual port of a virtual switch. When the system boots, and before any offload is configured, all packets from the virtual functions appear in ... WebFast-path operations on data, such as packet transmit/receive, are not mediated by the MC and are done directly using memory mapped regions in DPIO objects. Overview of DPAA2 Objects¶ The section provides a brief overview of some key DPAA2 objects. A simple scenario is described illustrating the objects involved in creating a network interfaces.
