Hello ASIX team, 

I have a custom board with the AX88279 chipset. I donwloaded the latest driver from the AX88279 product page which says supports running on Linux Kernel 6.9.0. I have setup an Ubuntu environment with the 6.9.0 kernel. 

I run the instructions in the "Readme" file. And in the Makefile I have the follwoing options enabled:

ENABLE_IOCTL_DEBUG = n

ENABLE_AUTODETACH_FUNC = n

ENABLE_MAC_PASS = n

ENABLE_INT_AGGRESSIVE = y

ENABLE_INT_POLLING = n

ENABLE_AUTOSUSPEND = n

ENABLE_TX_TASKLET = n

ENABLE_RX_TASKLET = n

ENABLE_PTP_FUNC = y

ENABLE_PTP_DEBUG = n

ENABLE_QUEUE_PRIORITY = n

I follow the build instructions:

1. make

2. sudo make install

3. sudo modprobe ax_usb_nic

4. sudo dmesg | tail -n 20

Then I check ethtool stats:

Every time the device comes up at 10Mb/s and Auto-negotiation as "off". 

I try to change the settings using "sudo ethtool -s enxf8e43b189a7e speed 1000 duplex full autoneg on" but the result looks the same every time, nothing changes. I have tried restarting PC, reconnecting device, but I am unable to change these settings. 

What can I do? I feel that I have tried everything but not having any success.
