I have also the same issue, but I have a Realtek card. Running ubuntu
15.10 and after suspend or restart it is saying network cable unplugged
very often. And network seems to go down everytime you suspend.
Unpluggin and plugging it sometimes help, but you may need to do it
multiple times.
Here is my network card information:
*-network

And I am having this kind of messages in dmesg:

(Note I removed my network card multiple times, and I was trying to restart the
network sometimes with sudo /etc/init.d/network-manager restart)
I read somewhere this may be a buggy Realtek driver. Or some other
issue, but seems to be very similar symptomps than the OP had.
Any advice? File a separate bug report?
