Title:
  hns: ethtool selftest crashes system

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Zesty:
  In Progress

Bug description:
  [Impact]
  Running ethtool selftest on an onboard NIC can crash the system

  [Test Case]
  On a HiSilicon D05 board:

  ubuntu@d05-3:~$ sudo ethtool -t enahisic2i1
  [sudo] password for ubuntu: 
  [  133.554255] hns-nic HISI00C2:01: Phy    Loopback test recv fail, cnt=0x0, 
budget=0x1
  The test result is FAIL
  The test extra info:
  Mac    Loopback test   0
  Serdes Loopback test   0
  Phy    Loopback test   3

  [Regression Risk]
  The fix is restricted to the hns driver's ethtool routines. Any regressions 
would be isolated to these HiSilicon platforms, and only during ethtool 
funcionality (i.e. workaround for regression would be don't-do-that).
