    "content": "Hi All,\n\nAttached is version 2 of a patchset to add a new API function to\nset the link status on kernel interfaces created with the KNI kernel\nmodule.\n\n-dan\n\nv2\n====\n\n* Fix bug where \"Fixed\" and \"AutoNeg\" were transposed in the link\n  status log message.\n\n* Add rte_kni_update_link() to\n\n* Add rte_kni_update_link() tests to kni_autotest\n\n* Update examples/kni to continuously monitor link status and\n  update the corresponding kernel interface with\n  rte_kni_update_link().\n\n* Minor improvements to examples/kni: Add log message showing how\n  to show/zero stats.  Improve zeroing statistics.\n\nNote that compains about patch 1/5, but this appears\nto be a bug with check-symbol-change or something.  If I move the\nfragment of the patch modifying to the bottom of\nthe patch file, it doesn't complain any more...  I just don't really\nhave time to investigate this right now.\n\nthanks\ndan\n\n> Hi All,\n> \n> The following patches are to add support for DPDK applications to be\n> able to change the carrier state of Linux network interfaces in the\n> KNI kernel module.\n> \n> The carrier state is changed by writing to the Linux /sys file:\n> /sys/devices/virtual/net/<name>/carrier, where <name> is the KNI\n> interface name.\n> \n> These patches supercede:\n> '[PATCH v2 10/10] kni: add API to set link status on kernel interface'\n>\n\n\nDan Gora (5):\n  kni: add API to set link status on kernel interface\n  kni: set default carrier state to 'off'\n  examples/kni: monitor and update link status continually\n  examples/kni: add log msgs to show and clear stats\n  examples/kni: improve zeroing statistics\n\n examples/kni/Makefile              |   2 +\n examples/kni/main.c                | 104 ++++++++++++++++-------------\n kernel/linux/kni/kni_misc.c        |   2 +\n kernel/linux/kni/kni_net.c         |   2 +\n lib/librte_kni/rte_kni.c           |  57 ++++++++++++++++\n lib/librte_kni/rte_kni.h           |  18 +++++\n lib/librte_kni/ |   6 ++\n test/test/test_kni.c               | 100 ++++++++++++++++++++++++++-\n 8 files changed, 244 insertions(+), 47 deletions(-)"
