Title:
  thunder: chip errata w/ multiple CQEs for a TSO packet

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

Bug description:
  [Impact]
  With small segment sizes, it is possible for the driver to free an SKB before transmitting it, potentially resulting in a crash.

  [Test Case]
  The test case for this is to use a small MTU (200) and mount an NFS exported directory. Create several (~4) 1M files w/ dd, then copy them locally. However, I have not been able to trigger the crash myself.

  [Regression Risk]
  Fix is upstream, so regressions will have upstream support. Fix is limited to a driver that is only applicable to the Cavium Thunder-X SoC, so risk is negligible to other platforms.
