This driver is used for Physical Function 15 (PF). 16 17 HiNIC3 devices support MSI-X interrupt vector for each Tx/Rx queue and 18 adaptive interrupt moderation. 19 20 HiNIC3 devices support also various offload features such as checksum offload, 21 TCP Transmit Segmentation Offload(TSO), Receive-Side Scaling(RSS) and 22 LRO(Large Receive Offload). 23 24 25 Supported PCI vendor ID/device IDs: 26 =================================== 27 28 19e5:1822 - HiNIC3 PF 29 30 31 Driver Architecture and Source Code: 32 ==================================== 33 34 hinic3_dev - Implement a Logical Network device that is independent from 35 specific HW details about HW data structure formats. 36 37 hinic3_hwdev - Implement the HW details of the device and include the components 38 for accessing the PCI NIC. 39 40 hinic3_hwdev contains the following components: 41 =============================================== 42 43 HW Interface: 44 ============= 45 46 The interface for accessing the pci device (DMA memory and PCI BARs). 47 (hinic3_hw_if.c, hinic3_hw_if.h) 48 49 Configuration Status Registers Area that describes the HW Registers on the 50 configuration and status BAR0.
