Is the cable perhaps 1.4 type with built-in Ethernet? Wonder if that
might have something to do with it too. The SmartTV might be doing
the communication attempts. Maybe it is trying to tattle on you for
using video that it /thinks/ is breaking digital rights.. maybe
something else entirely. If the kernel is making the HTTP calls, it
might be under direction of the video driver that is able to network
with the screen via the HDMI cable.
