We ran into this issue a long time ago since OpenE at the
time did not support the 82599 Intel Driver (Internally
called Niantic). This Intel driver required a
newer level of Linux that OpenE did not support
at the time....OpenE provided the patch as they probably have given to you
which will fix the issue.....but the newer releases of OpenE include the correct
driver by default.
