Bug description:
  SRU Justification

  Impact: Under certain workloads a BUG in the xen-netfront driver is
  getting triggered.

  Fix: Remove the offending BUG, and a related BUG which would have also
  been triggered by the same conditions.

  Test Case: This bug has only been seen under certain workloads
  involving haproxy and has proved challenging to reproduce. The fix has
  been verified by an affected user, with the BUG replaced by a WARN to
  ensure that the conditions which would have triggered the bug were
  actually encountered.

  Regression Potential: The fix has been verified and acked upstream.
  Removing the BUGs will not affect cases which were not crashing
  previously, and cases which were crashing can't really be made much
  worse.

  I run ubuntu servers 13.04, 13.10, and 14.04 on the AWS cloud.
  Whenever I install haproxy and nginx on the same server, after hitting
  it for a while, a kernel panic is caused. However, the kernel panic
  does not show up in ubuntu 12.04.  The kernel panic is pasted at the
  end of the attachment.
