+============================================================
+Linux Kernel Driver for Huawei Intelligent NIC(HiNIC) family
+============================================================
+
+Overview:
+=========
+HiNIC is a network interface card for the Data Center Area.
+
+The driver supports a range of link-speed devices (10GbE, 25GbE, 40GbE, etc.).
+The driver supports also a negotiated and extendable feature set.
+
+Some HiNIC devices support SR-IOV. This driver is used for Physical Function
+(PF).
+
+HiNIC devices support MSI-X interrupt vector for each Tx/Rx queue and
+adaptive interrupt moderation.
+
+HiNIC devices support also various offload features such as checksum offload,
+TCP Transmit Segmentation Offload(TSO), Receive-Side Scaling(RSS) and
+LRO(Large Receive Offload).
+
+
+Supported PCI vendor ID/device IDs:
+===================================
+
+19e5:1822 - HiNIC PF
+
+
+Driver Architecture and Source Code:
+====================================
+
+hinic_dev - Implement a Logical Network device that is independent from
+specific HW details about HW data structure formats.
+
+hinic_hwdev - Implement the HW details of the device and include the components
+for accessing the PCI NIC.
+
+hinic_hwdev contains the following components:
+===============================================
+
+HW Interface:
+=============
+
+The interface for accessing the pci device (DMA memory and PCI BARs).
+(hinic_hw_if.c, hinic_hw_if.h)
+
+Configuration Status Registers Area that describes the HW Registers on the
+configuration and status BAR0. (hinic_hw_csr.h)
+
+MGMT components:
+================
+
+Asynchronous Event Queues(AEQs) - The event queues for receiving messages from
+the MGMT modules on the cards. (hinic_hw_eqs.c, hinic_hw_eqs.h)
+
+Application Programmable Interface commands(API CMD) - Interface for sending
+MGMT commands to the card. (hinic_hw_api_cmd.c, hinic_hw_api_cmd.h)
+
+Management (MGMT) - the PF to MGMT channel that uses API CMD for sending MGMT
+commands to the card and receives notifications from the MGMT modules on the
+card by AEQs. Also set the addresses of the IO CMDQs in HW.
+(hinic_hw_mgmt.c, hinic_hw_mgmt.h)
+
+IO components:
+==============
+
+Completion Event Queues(CEQs) - The completion Event Queues that describe IO
+tasks that are finished. (hinic_hw_eqs.c, hinic_hw_eqs.h)
+
+Work Queues(WQ) - Contain the memory and operations for use by CMD queues and
+the Queue Pairs. The WQ is a Memory Block in a Page. The Block contains
+pointers to Memory Areas that are the Memory for the Work Queue Elements(WQEs).
+(hinic_hw_wq.c, hinic_hw_wq.h)
+
+Command Queues(CMDQ) - The queues for sending commands for IO management and is
+used to set the QPs addresses in HW. The commands completion events are
+accumulated on the CEQ that is configured to receive the CMDQ completion events.
+(hinic_hw_cmdq.c, hinic_hw_cmdq.h)
+
+Queue Pairs(QPs) - The HW Receive and Send queues for Receiving and Transmitting
+Data. (hinic_hw_qp.c, hinic_hw_qp.h, hinic_hw_qp_ctxt.h)
+
+IO - de/constructs all the IO components. (hinic_hw_io.c, hinic_hw_io.h)
+
+HW device:
+==========
+
+HW device - de/constructs the HW Interface, the MGMT components on the
+initialization of the driver and the IO components on the case of Interface
+UP/DOWN Events. (hinic_hw_dev.c, hinic_hw_dev.h)
+
+
+hinic_dev contains the following components:
+===============================================
+
+PCI ID table - Contains the supported PCI Vendor/Device IDs.
+(hinic_pci_tbl.h)
+
+Port Commands - Send commands to the HW device for port management
+(MAC, Vlan, MTU, ...). (hinic_port.c, hinic_port.h)
+
+Tx Queues - Logical Tx Queues that use the HW Send Queues for transmit.
+The Logical Tx queue is not dependent on the format of the HW Send Queue.
+(hinic_tx.c, hinic_tx.h)
+
+Rx Queues - Logical Rx Queues that use the HW Receive Queues for receive.
+The Logical Rx queue is not dependent on the format of the HW Receive Queue.
+(hinic_rx.c, hinic_rx.h)
+
+hinic_dev - de/constructs the Logical Tx and Rx Queues.
+(hinic_main.c, hinic_dev.h)
+
+
+Miscellaneous
+=============
+
+Common functions that are used by HW and Logical Device.
+(hinic_common.c, hinic_common.h)
+
+

+with a supported adapter, email the specific information related to the issue to
