RTL8153 connected via ASM1042A is used in Dell's TB15 and TB16 docks. So everyone using these docks is probably affected.

What happens?
- boot
- connect to network
- issue dmesg via ssh on a remote computer (not necessary but breakage simply occurs after some time, some people report that this occurs on high throughput)
- get errors like "bad mac" on ssh or ssl
- ethernet link is not usable anymore

If I connect a RTL8153 to a different USB Port (not ASM1042A) everything works as expected.

Ansis Atteka already digged into this issue. He wrote a mail about this here which may help any developer who looks into this:

Trace and dmesg retrieved from launchpad. Can still reproduce this with 4.11.3

I am able to test any provided patches :)

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
