  thunderx nics fail to establish link

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Xenial:
  Fix Committed

Bug description:
  When connected to certain switches, Cavium ThunderX nodes will occasionally 
fail to establish a link. On one setup (using a Cisco 10G switch), we're seeing 
a failure rate of about 20%.

  Manually reloading the driver modules - or rebooting - is required to

  A fix is now available in linux-next that greatly reduces (though it
  doesn't 100% eliminate) the frequency of occurrences (2% vs. 20%, in
  my case). Investigation continues to identify a resolution for the
  remaining cases.

  [Test Case]
  Connect Cavium ThunderX systems to a known bad switch, and put them in a 
reboot loop. In my test, I use the maas cli to release/acquire/deploy systems, 
and wait for a node to enter the deployment failure state.

  [Regression Risk]
  The fix is upstream, and internal to a specific driver only used on Cavium 
ThunderX systems.
