Public bug reported:
I have a Dell Precision 5520 laptop with a Thunderbolt USB 3.1 type C
port that I connect to a Dell TB15 docking station connected with an
Ethernet cable.
Network manager section for ethernet connections is all grayed out, and
it says "device unsupported".
USB subsystem seems to detect the device just fine:

The ethernet device is created, but DOWN:

Additionally, I noticed a Huawei E3272 LTE modem USB dongle also doesn't
work exactly *the same way*.
When I insert the dongle, its LED turns on after a few seconds,
indicating the modem initialized properly. The network interface
(enx582c80139263) is created, but in a down state. Then if I manually
make it UP and run dhclient, I get Internet connectivity just fine.
Ubuntu 17.04, all updates applied as of today.
I tried purging network-manager package and installing again but it didn't help.
** Affects: network-manager (Ubuntu)
Importance: Undecided
Status: New
** Summary changed:
- Network manager says my ethernet device is not supported, but I can connect
manually
+ Network manager says my ethernet device is not supported, though I can
connect manually
** Description changed:
I have a Dell Precision 5520 laptop with a Thunderbolt USB 3.1 type C
port that I connect to a Dell TB15 docking station connected with an
Ethernet cable.
Network manager section for ethernet connections is all grayed out, and
it says "device unsupported".

The ethernet device is created, but DOWN:
```
ifconfig -a

Manually setting up connection works:
```
$ sudo ifconfig eth0 up
$ sudo dhclient eth0
$ ifconfig -a

Additionally, I noticed a Huawei E3272 LTE modem USB dongle also doesn't
work exactly *the same way*.
When I insert the dongle, its LED turns on after a few seconds,
indicating the modem initialized properly. The network interface
(enx582c80139263) is created, but in a down state. Then if I manually
make it UP and run dhclient, I get Internet connectivity just fine.

I tried purging network-manager package and installing again but it didn't
help.
** Summary changed:
- Network manager says my ethernet device is not supported, though I can
connect manually
+ Network manager says my USB-based ethernet devices are not supported, though
I can connect manually
