Bug Description

Network interface (NIC) won't respond or work after resuming from suspend to RAM. The device will still appear under commands such as `lshw -c network` or `lspci`, but the network communication will be nonetheless broken.

In my particular case, this happens with a "88E8056 PCI-E Marvell Yukon 2 Gigabit Ethernet Controller". Removing the driver module and adding it back again solves the problem.

```
sudo modprobe -r sky2 && sudo modprobe sky2
```

Ubuntu 20.04 was also affected by this bug and, from a simple search, this could be a more general regression bug since it affected other drivers in previous releases, e.g. r8169 in Ubuntu MATE 16.04:
