Improve zeroing statistics.\n\nNote that checkpatches.sh 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 rte_kni_version.map 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> https://mails.dpdk.org/archives/dev/2018-August/110383.html\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/rte_kni_version.map | 6 ++\n test/test/test_kni.c | 100 ++++++++++++++++++++++++++-\n 8 files changed, 244 insertions(+), 47 deletions(-)" }
