Good to hear.

Could you also test a current kernel?

I'd like to see two tests if you can do them
1 - check what happens if you suspend/hibernate the whole system
Does autosuspend cope with that?
2 - does it correctly deal with device parameters, eg. change of IP,
duplex vs. simplex, link speed etc...

Which drivers do you want it for?
If this patch turns out well, I'll extend it to cdc-eem and maybe rndis.
Beyond that I am open to suggestions.
