This adds support for the current generation of ASIX network adapter chips, which are based on the AX88179A. This includes the AX88179A/B (1GBit-PHY), AX88772D/E (100MBit) and AX88279 (2.5GBit). The AX179A-based chips all provide both a CDC-NCM compatible USB interface, and a proprietary vendor interface with more features. By default, the proprietary vendor interface is not active and Linux will load the CDC-NCM driver to support the devices. If the ax88179_178a module is configured by the OS to have precedence over CDC-NCM, then this driver will switch the device to use the vendor interface, and the device will be controlled by the ax88179_178a driver when the device is probed again after an automatic reset of the device bringing up the vendor interface. The following hardware was tested: Delock 66046 2.5GBit adapter (AX88279, FW: 1.2.0.0) TP-Link UE306 1GBit adapter (AX88179B, FW: 1.3.0.0) Renkforce RF-4708614 1GBit adapter (AX88179A, FW: 1.0.4.0) UGREEN CR110 100MBit adapter (AX88722E, FW: 1.3.0.0) The driver supports the following features - EEE - TCP segmentation offload - VLAN filtering/tagging offload (NETIF_F_HW_VLAN_CTAG_FILTER, NETIF_F_HW_VLAN_CTAG_RX/TX) - RX/TX checksum offload - FC/Pause configuration - EEPROM read access The code is based on the ASIX 4.1.0 out-of-tree driver published under the GPL,, the aqc111 driver which provides support for the AX88279A, and some tracing of USB-transfers of the Windows-driver.
