Hi All,

Attached is version 2 of a patchset to add a new API function to
set the link status on kernel interfaces created with the KNI kernel



* Fix bug where "Fixed" and "AutoNeg" were transposed in the link
  status log message.

* Add rte_kni_update_link() to rte_kni_version.map

* Add rte_kni_update_link() tests to kni_autotest

* Update examples/kni to continuously monitor link status and
  update the corresponding kernel interface with

* Minor improvements to examples/kni: Add log message showing how
  to show/zero stats.  Improve zeroing statistics.

Note that checkpatches.sh compains about patch 1/5, but this appears
to be a bug with check-symbol-change or something.  If I move the
fragment of the patch modifying rte_kni_version.map to the bottom of
the patch file, it doesn't complain any more...  I just don't really
have time to investigate this right now.
