> ChangeLog:
> Implement .reset_resume support to retain a live network connection
> during suspend despite USB power loss.
> - rework operation to reference cached data in mcs7830_data and
>   netdev->dev_addr 
> - update netdev->dev_addr only in case new MAC was set successfully
> . Tests done:
>   . ethtool -d pre-/post-suspend: register values match
>   . running ssh session suspend, resume: works
>   . ifdown device, suspend, resume: works
>   . ifup, suspend, unplug, resume: WORKS (eth1 is removed, re-ifup of eth1
>     after card replug works)
>   . verified identical MAC in ifconfig post-resume
>     (ok, should be verified on network side to be fully certain...)
>

> Keywords: suspend resume network connection dead interface down
