Subject: [PATCH V2 net-next 0/8] Hisilicon Network Subsystem 3 Ethernet Driver

This patch-set contains the support of the HNS3 (Hisilicon Network Subsystem 3)
Ethernet driver for hip08 family of SoCs and future upcoming SoCs.

Hisilicon's new hip08 SoCs have integrated ethernet based on PCI Express and
hence there was a need of new driver over the previous HNS driver which is 
already part of the Linux mainline. This new driver is NOT backward
compatible with HNS.

This current driver is meant to control the Physical Function and there would
soon be a support of a separate driver for Virtual Function once this base PF
driver has been accepted. Also, this driver is the ongoing development work and
HNS3 Ethernet driver would be incrementally enhanced with more new features.

 1. Basic Rx and Tx functionality 
 2. TSO support
 3. Ethtool support
 4. Debugfs support 
 5. HNAE framework and hardware compatability layer
 6. Scheduler and Shaper support in transmit function
 7. MDIO support
