Re: [PATCH 4/4] MCS7830 USB-Ether: resume _with_ working link, via .reset_resume support

From: Andreas Mohr <redacted>
Date: Sun, 31 Jan 2010 13:58:42 +0100

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
