After waking up from suspend, if you run:

sudo modprobe -r sky2; sleep 3; sudo modprobe sky2

Does it start working OK?

Actually, yes. But I don't want to do this everytime I suspend. Is there a way to do this automatically?

Ignore the the "does" word there, bad paste. OK we now have a script to fix the ethernet. Does this work OK if you run:

sudo ethernetfix

Does it make the ethernet work OK? If so, we can make it run when the system wakes up

That does make the ethernet work. How do I make this run on waking up?

A quick websearch shows how. You want to run the script at wake up
https://askubuntu.com/questions/226278/run-script-on-wakeup

Something like this.

Thanks actionparsnip, that solved my question.

Dead simple. You can add other junk to that script too
