Comment 0 for bug 1798921

Bug very similar to #1752772 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1752772) but affecting the sky2 driver instead of r8169.

After system suspend the ethernet connection stops working. The card is still up and the modem can see it is connected, but the card doesn't get an ip address. Ifconfig down/up and restarting network-manager does not solve the issue. Similarly to the other bug, "sudo modprobe sky2 -r" an then "sudo modprobe sky2" solves the issue.
