Ethernet through the dock?

[Zebulon Walton]

I received my eBay dock today:

https://www.ebay.com/itm/5-in-1-USB-3-0-...4211141163

It basically seems to work. It's powering the Pinephone when a charger is hooked up. The built-in gigabit ethernet adapter works and the USB ports do as well (though all those ports would be limited to USB 2 speeds due to the Pinephone hardware). I have not tested the HDMI port.

The gigabit ethernet comes up with the name "enx00e09901ad68". (I miss the old ethX designations!) Although the wired connection seems quite speedy I have not been able to verify the connection speed. There are no LEDs on the ethernet port to indicate speed or even connection status. Normally I'd use ethtool on the command line for this but it is not displaying the link speed, only that the link is present.

Code:

[root@mobian mobian]$ ethtool enx00e09901ad68
Settings for enx00e09901ad68:
        Current message level: 0x00000007 (7)
                               drv probe link
    Link detected: yes

It should be possible to look at the speed via the /sys pseudo filesystem, but that doesn't work either:

Code:

[root@mobian mobian]$ cat /sys/class/net/enx00e09901ad68/speed
cat: /sys/class/net/enx00e09901ad68/speed: Invalid argument

Both the above methods were run as root. They do show the link speed on my desktop Ubuntu system, so I'm not sure what's going on with this.

EDIT:

Using "ethtool -i enx00e09901ad68" returns the following:

Code:

[root@mobian mobian]$ ethtool -i enx00e09901ad68
driver: cdc_ether
version: 5.10-sunxi64
firmware-version: CDC Ethernet Device
expansion-rom-version:
bus-info: usb-1c1a000.usb-1.4
supports-statistics: no
supports-test: no
supports-eeprom-access: no
supports-register-dump: no
supports-priv-flags: no

This is an Ethernet-over-USB device with an emulated gigabit adapter, which is probably why the usual ways of finding the link speed are not working.
