The Physical Function driver is already part of the Linux mainline. This VF driver has its Hardware Compatibility Layer and has commom/unified ENET layer/client/ethtool code with the PF driver. The basic architecture of VF driver is derivative of the PF driver. Just like PF driver, this driver is also PCI Express based. This driver is the ongoing development work and HNS3 VF Ethernet driver would be incrementally enhanced with more new features. High Level Architecture: [ Ethtool ] | [ Ethernet Client ] ...
