Hi All, Attached is version 5 of a patchset to add a new API function to set the link status on kernel interfaces created with the KNI kernel module. v5 ==== * Update Kernel NIC Interface document with new rte_kni option, move kernel module parameter description here from KNI sample app document, general cleanup. * Update Kernel NIC Interface sample application (kni) document with new command line parameter, remove documentation for rte_kni kernel module but add reference to it, general cleanup. * Change link status change sample rate for KNI example app to 500ms from 100ms. * Fix bug in parameter parsing in v4 in rte_kni kernel module. * Fix output formatting of optional parameters for rte_kni with modinfo. * Fix permissions of optional parameters for rte_kni. * Squash patch to add test for rte_kni_update_link into patch introducing the API function. > v4 > ==== > * Rework rte_kni_update_link to only take linkup/linkdown as parameter, > return previous link state, and remove log messages. > > * Update patch to set default carrier state to make default carrier > state configurable by passing the 'carrier=[on|off]' option to > the rte_kni kernel module. This is necessary in order to allow > applications which use KNI as pure virtual interfaces without > corresponding physical ethernet port to use the interfaces without > having to set the carrier state to 'on' via rte_kni_update_link() > or by writing to /sys/devices/virtual/net/<ifaceX>/carrier. > Note that the default is 'off'. > > * Add command line flag '-m' to examples/kni to continuously monitor > and update the KNI interface link status according to the link > status of the corresponding physical ethernet port. > > > v3 > ==== > * Use separate function to test rte_kni_update_link() in 'test' app. > > * Separate changes to 'test' app into separate patch to facilitate > possible merge with https://patches.dpdk.org/patch/44730/ > > * Remove changes to set KNI interfaces to 'up' in example/kni > > 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 Dan Gora (5): kni: add API to set link status on kernel interface kni: set default carrier state of interface examples/kni: monitor and update link status continually examples/kni: add log msgs to show and clear stats examples/kni: improve zeroing statistics .../prog_guide/kernel_nic_interface.rst | 203 ++++++++++---- .../sample_app_ug/kernel_nic_interface.rst | 249 +++++++++++------- examples/kni/Makefile | 2 + examples/kni/main.c | 92 ++++++- kernel/linux/kni/kni_dev.h | 3 + kernel/linux/kni/kni_misc.c | 57 +++- kernel/linux/kni/kni_net.c | 5 + lib/librte_kni/rte_kni.c | 41 +++ lib/librte_kni/rte_kni.h | 20 ++ lib/librte_kni/rte_kni_version.map | 6 + test/test/test_kni.c | 77 ++++++ 11 files changed, 598 insertions(+), 157 deletions(-)
