Hello world :-)

I have this nice USB 3.0/C UNITEK Y-3083B USB HUB + GigaBit Ethernet device
that expands my laptop or smartphone cards and provides ue0 Ethernet
connectivity. However always after some time network stops and I have to put
that ue0 interface down and up. That never happens on built-in Ethernet card
em0 (Intel(R) PRO/1000 Network Connection).

Any hints welcome :-)
Tomek
