MCS7830 USB-Ether: resume _with_ working link, via .reset_resume support
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
