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: > '[PATCH v2 10/10] kni: add API to set link status on kernel interface' > https://mails.dpdk.org/archives/dev/2018-August/110383.html Dan Gora (5): kni: add API to set link status on kernel interface kni: set default carrier state to 'off' examples/kni: monitor and update link status continually examples/kni: add log msgs to show and clear stats examples/kni: improve zeroing statistics examples/kni/Makefile | 2 + examples/kni/main.c | 104 ++++++++++++++++------------- kernel/linux/kni/kni_misc.c | 2 + kernel/linux/kni/kni_net.c | 2 + lib/librte_kni/rte_kni.c | 57 ++++++++++++++++ lib/librte_kni/rte_kni.h | 18 +++++ lib/librte_kni/rte_kni_version.map | 6 ++ test/test/test_kni.c | 100 ++++++++++++++++++++++++++- 8 files changed, 244 insertions(+), 47 deletions(-) -- 2.19.0
