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
module.

-dan

v2
====

* 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
  rte_kni_update_link().

* 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.

thanks
dan

Hi All,

The following patches are to add support for DPDK applications to be
able to change the carrier state of Linux network interfaces in the
KNI kernel module.

The carrier state is changed by writing to the Linux /sys file:
/sys/devices/virtual/net/<name>/carrier, where <name> is the KNI
interface name.

These patches supercede:
