This patch-set contains the support of the HNS3 (Hisilicon Network Subsystem 3)
Virtual Function Ethernet driver for hip08 family of SoCs. 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. It also has support of mailbox to
communicate with the HNS3 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.
