ENETC is a multi-port virtualized Ethernet controller supporting GbE designs and Time-Sensitive Networking (TSN) functionality. ENETC is operating as an SR-IOV multi-PF capable Root Complex Integrated Endpoint (RCIE). As such, it contains multiple physical (PF) and virtual (VF) PCIe functions, discoverable by standard PCI Express. Introduce basic PF and VF ENETC ethernet drivers. The PF has access to the ENETC Port registers and resources and makes the required privileged configurations for the underlying VF devices. Common functionality is controlled through so called System Interface (SI) register blocks, PFs and VFs own a SI each. Though SI register blocks are almost identical, there are a few privileged SI level controls that are accessible only to PFs, and so the distinction is made between PF SIs (PSI) and VF SIs (VSI). As such, the bulk of the code, including datapath processing, basic h/w offload support and generic pci related configuration, is shared between the 2 drivers and is factored out in common source files (i.e. enetc.c). Major functionalities included (for both drivers): MSI-X support for Rx and Tx processing, assignment of Rx/Tx BD ring pairs to MSI-X entries, multi-queue support, Rx S/G (Rx frame fragmentation) and jumbo frame (up to 9600B) support, Rx paged allocation and reuse, Tx S/G support (NETIF_F_SG), Rx and Tx checksum offload, PF MAC filtering and initial control ring support, VLAN extraction/ insertion, PF Rx VLAN CTAG filtering, VF mac address config support, VF VLAN isolation support, etc. Signed-off-by: Claudiu Manoil <claudiu.manoil@nxp.com> Signed-off-by: David S.
