Subject: [PATCH V2 net-next 4/8] net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support
This patch adds the support of Hisilicon Network Subsystem Accceleration
Engine and common operations to access it. This layer provides access to the
hardware configuration, hardware statistics. This layer is also
responsible for triggering the initialization of the PHY layer through
the below MDIO layer.
